2. Intent to Kill

The defendant must have the specific intent to cause death or serious injury to another person.

What to prove: Evidence must demonstrate that the defendant intended to kill the victim rather than just cause harm or inflict injury.

3. Malice Aforethought

The act must be conducted with a disregard for human life, reflecting a depraved mindset.
