Final answer:
Self-defense is not an element of proof for the offense of murder; it is a possible defense. The elements of proof for a murder charge generally consist of motive, intent, and actus reus.
Step-by-step explanation:
The question asks which of the following is not an element of proof for the offense of murder: 1) Motive 2) Intent 3) Actus reus 4) Self-defense 5) All of the above. Self-defense is not an element of proof for the offense of murder but rather a potential defense to a charge of murder. The elements of proof typically include motive, intent, and actus reus (the actual commission of the crime).
Moreover, self-defense is a legally recognized reason that can excuse or justify the act of killing someone. If a person acts in self-defense and those actions meet specific legal criteria, the killing may be considered justifiable and therefore not constitute murder.
The standard of proof in a criminal trial, especially in a capital homicide case, is to establish evidence that convinces beyond a reasonable doubt. This means that there must be sufficient evidence for a reasonable person to have no doubt that might affect their belief in the guilt of the defendant.
