Begin with criminal-law doctrine
Homicide analysis begins with the jurisdiction's enacted categories rather than one generic ladder. Texas murder has multiple statutory paths; capital murder requires the specified murder form plus a listed circumstance. Under subsection d of the pinned murder provision, sudden passion arising from adequate cause is raised at the punishment stage, is proved by the defendant by a preponderance of the evidence, and reduces murder grading from a first-degree felony to a second-degree felony. It is not an element of murder, not a defense to prosecution, not the culpable mental state for manslaughter, and not a separate lesser offense. Manslaughter instead requires reckless causation, while criminally negligent homicide requires criminal negligence. Recklessness means awareness and conscious disregard of the qualifying risk; criminal negligence means the actor ought to have been aware.
Murder
The murder provision supplies distinct intentional or knowing, serious-bodily-injury, felony, and specified controlled-substance paths. Verbatim statutory text: “Tex. Penal Code Sec. 19.02. MURDER. (a) In this section: (1) "Adequate cause" means cause that would commonly produce a degree of anger, rage, resentment, or terror in a person of ordinary temper, sufficient to render the mind incapable of cool reflection. (2) "Sudden passion" means passion directly caused by and arising out of provocation by the individual killed or another acting with the person killed which passion arises at the time of the offense and is not solely the result of former provocation. (b) A person commits an offense if the person: (1) intentionally or knowingly causes the death of an individual; (2) intends to cause serious bodily injury and commits an act clearly dangerous to human life that causes the death of an individual; (3) commits or attempts to commit a felony, other than manslaughter, and in the course of and in furtherance of the commission or attempt, or in immediate flight from the commission or attempt, the person commits or attempts to commit an act clearly dangerous to human life that causes the death of an individual; or (4) knowingly manufactures or delivers a controlled substance included in Penalty Group 1-B under Section 481.1022, Health and Safety Code, in violation of Section 481.1123, Health and Safety Code, and an individual dies as a result of injecting, ingesting, inhaling, or introducing into the individual's body any amount of the controlled substance manufactured or delivered by the actor, regardless of whether the controlled substance was used by itself or with another substance, including a drug, adulterant, or dilutant. (c) Except as provided by Subsection (d), an offense under this section is a felony of the first degree. (d) At the punishment stage of a trial, the defendant may raise the issue as to whether he caused the death under the immediate influence of sudden passion arising from an adequate cause. If the defendant proves the issue in the affirmative by a preponderance of the evidence, the offense is a felony of the second degree. (e) It is a defense to prosecution under Subsection (b)(4) that the actor's conduct in manufacturing or delivering the controlled substance was authorized under Chapter 481, Health and Safety Code, or other state or federal law.” Source: Tex.

Capital murder
The capital-murder provision begins with a specified murder path and requires an additional listed circumstance. Verbatim statutory text: “Tex. Penal Code Sec. 19.03. CAPITAL MURDER. (a) A person commits an offense if the person commits murder as defined under Section 19.02(b)(1) and: (1) the person murders a peace officer or fireman who is acting in the lawful discharge of an official duty and who the person knows is a peace officer or fireman; (2) the person intentionally commits the murder in the course of committing or attempting to commit kidnapping, burglary, robbery, aggravated sexual assault, arson, obstruction or retaliation, or terroristic threat under Section 22.07(a)(1), (3), (4), (5), or (6); (3) the person commits the murder for remuneration or the promise of remuneration or employs another to commit the murder for remuneration or the promise of remuneration; (4) the person commits the murder while escaping or attempting to escape from a penal institution; (5) the person, while incarcerated in a penal institution, murders another: (A) who is employed in the operation of the penal institution; or (B) with the intent to establish, maintain, or participate in a combination or in the profits of a combination; (6) the person: (A) while incarcerated for an offense under this section or Section 19.02, murders another; or (B) while serving a sentence of life imprisonment or a term of 99 years for an offense under Section 20.04, 22.021, or 29.03, murders another; (7) the person murders more than one person: (A) during the same criminal transaction; or (B) during different criminal transactions but the murders are committed pursuant to the same scheme or course of conduct; (8) the person murders an individual under 10 years of age; (9) the person murders an individual 10 years of age or older but younger than 15 years of age; or (10) the person murders another person in retaliation for or on account of the service or status of the other person as a judge or justice of the supreme court, the court of criminal appeals, a court of appeals, a district court, a criminal district court, a constitutional county court, a statutory county court, a justice court, or a municipal court. (b) An offense under this section is a capital felony. (c) If the jury or, when authorized by law, the judge does not find beyond a reasonable doubt that the defendant is guilty of an offense under this section, he may be convicted of murder or of any other lesser included offense. (d) For purposes of Subsection (a)(1), the actor is presumed to have known the person murdered was a peace officer or fireman if the person was wearing a distinctive uniform or badge indicating the person's employment as a peace officer or fireman.” Source: Tex.

Manslaughter
The manslaughter provision requires recklessly causing an individual's death. Verbatim statutory text: “Tex. Penal Code Sec. 19.04. MANSLAUGHTER. (a) A person commits an offense if he recklessly causes the death of an individual. (b) An offense under this section is a felony of the second degree, except that the offense is a felony of the first degree if it is shown on the trial of the offense that the defendant committed an offense under Section 28.09 and that conduct caused the death of an individual.” Source: Tex.

Criminally negligent homicide
The criminally negligent homicide provision requires causing death by criminal negligence. Verbatim statutory text: “Tex. Penal Code Sec. 19.05. CRIMINALLY NEGLIGENT HOMICIDE. (a) A person commits an offense if he causes the death of an individual by criminal negligence. (b) An offense under this section is a state jail felony.” Source: Tex.

Pin the synthetic facts
A synthetic classification packet presents four variants over a death: intentional or knowing causation; murder plus punishment-stage sudden-passion evidence; reckless causation; and failure to perceive a qualifying risk. Provocation, timing, warnings, medical evidence, and contrary accounts remain disputed.
Work the element application
The first row classifies intentional or knowing causation under the charged murder path and keeps ordinary first-degree grading. The second row retains that murder conviction but separately tests sudden passion arising from adequate cause at punishment; only if the defendant proves it by a preponderance does grading fall to a second-degree felony. The third row classifies reckless causation as manslaughter, not sudden passion. The fourth classifies criminal negligence separately. Capital murder still requires the referenced murder form plus a listed circumstance, and every path retains causation and its burden.
Read the populated offense record
The homicide table contains a classification row for intentional or knowing murder, murder with punishment-stage sudden-passion mitigation, reckless manslaughter, and criminally negligent homicide. It records liability stage, punishment stage, required culpability, sudden-passion and adequate-cause evidence, burden actor, proof standard, causation, base grade, mitigated grade, aggravating circumstance, contrary proof, and unresolved status. The record contains 19 populated rows.

Read the complete record
The complete record keeps sources, stated facts, and questions for review separate. Pinned sources: Verbatim snapshot authority. Tex. Penal Code § 19.02: Murder. Tex. Penal Code § 19.03: Capital murder. Tex. Penal Code § 19.04: Manslaughter. Tex. Penal Code § 19.05: Criminally negligent homicide. Synthetic facts: Classroom facts only. Intentional or knowing variant: Actor causes a death with the conscious objective or awareness required by the charged murder path. Sudden-passion variant: The same murder conviction includes punishment-stage evidence of sudden passion arising from adequate cause. Reckless variant: Actor consciously disregards a substantial and unjustifiable death risk. Criminal-negligence variant: Actor ought to perceive a substantial and unjustifiable death risk but does not. Evidence: Messages, warnings, timing, provocation evidence, medical evidence, and contrary accounts remain disputed. Element trace: Questions, evidence pointers, and bounded comparisons. Intentional or knowing murder: Liability-stage offense path; prove conduct, death, intentional or knowing culpability, and causation; ordinarily first-degree felony grading. Murder with sudden passion: Same murder offense; at punishment only, defendant proves sudden passion arising from adequate cause by a preponderance; if proved, grading falls from first-degree to second-degree felony. Reckless manslaughter: Separate liability-stage offense requiring reckless causation; sudden passion is not its culpable mental state. Criminally negligent homicide: Separate liability-stage offense requiring criminal negligence rather than conscious disregard. Capital murder: First prove the referenced murder form, then the alleged aggravating circumstance. Common-law comparison: Degree labels vary by jurisdiction and must not replace Texas's enacted categories and grades.
Narrow summary
Classify the enacted homicide path first: sudden passion is defendant-proved punishment-stage mitigation of murder grading, never manslaughter's mental state, a prosecution defense, or a separate lesser offense.
