Which degree of murder includes attempted murder?

First-degree murder is defined as a premeditated act with the intent to kill. This is the most serious charge and encompasses planned and deliberate actions taken to bring about someone's death. The nature of this degree is that it includes "attempted murder" because if someone intended to kill another person and took significant steps toward that intent but ultimately did not succeed in causing death, it still reflects the premeditated intent required for first-degree murder.

In contrast, second-degree murder typically involves a disregard for human life but lacks the premeditation of the first degree, while third-degree murder involves acts that are dangerous to others without the intention to kill. Therefore, attempted murder aligns with the intent and premeditated aspect of first-degree murder, solidifying its inclusion under that category.
