First-degree murder — premeditation & deliberation

The rule

First-degree murder requires an intentional killing that is both premeditated (thought about in advance) and deliberate (formed in a cool and reflective state of mind). No fixed time is required; even a brief moment of reflection satisfies premeditation in most jurisdictions.

In plain English

The mental state that separates first-degree from second-degree murder is a decision to kill made with some reflection, not on sudden impulse.

The trap

Heat-of-passion facts negate deliberation and drop the crime to voluntary manslaughter, not second-degree murder.
