What does involuntary manslaughter involve?

Involuntary manslaughter is characterized by unintentional killing that occurs due to reckless behavior or gross negligence. This means that the individual did not have the intention to kill or cause harm but acted in a way that demonstrated a disregard for human life or a substantial risk of serious harm. This could involve situations where a person engages in risky conduct that unintentionally leads to another person's death.

In contrast, the other options represent different legal concepts. Intentional killing refers to murder, where there is a clear intent to cause death. Self-defense killing relates to using reasonable force to protect oneself from imminent harm, which can sometimes be legally justified and not classified as manslaughter. Assisting in suicide involves helping someone to end their own life, which is a different legal issue and is not classified under the category of involuntary manslaughter.
