Intentionally committing acts knowing they will cause death or great bodily harm, without lawful justification, is referred to as _____.

The term that describes the intentional commission of acts that one knows will likely result in death or great bodily harm, without any lawful justification, is first-degree murder. This classification reflects the deliberate and premeditated nature of the act, which signifies a conscious choice to cause harm or death.

First-degree murder typically requires that the perpetrator had a clear intention to kill or to cause serious injury, distinguishing it from other forms of homicide which may arise under less culpable circumstances. For example, while second-degree murder may involve intent to kill, it generally lacks the planning and premeditation that characterize first-degree scenarios. Similarly, voluntary manslaughter involves provocation or heat of passion, and involuntary manslaughter typically arises in situations where the death was unintentional, often due to reckless behavior rather than a conscious intent to kill. This makes first-degree murder the appropriate answer for this question.
