What is the legal definition of "self-defense"?

The legal definition of "self-defense" centers around the concept of using reasonable force to protect oneself from imminent harm or danger. This principle allows individuals the right to act in defense of their own safety when faced with a threatening situation. The use of reasonable force implies that the response to the threat is proportional; excessive force is not justified under the legal definition. This framework is essential in many legal systems as it underscores individual rights to personal safety while also setting boundaries on acceptable forms of self-defense.

The other options may contain elements that are related to personal safety but do not accurately reflect the legal criteria for self-defense. For instance, the idea of protecting belongings does not carry the same legal weight as protecting one's physical self from harm, as self-defense is primarily concerned with human safety rather than property. Additionally, approval of another person's actions is not necessary for self-defense; the focus is on the individual's response to immediate threat rather than seeking approval or justification from others. Lastly, suggesting legal justification for aggressive behavior does not align with the principle of self-defense, which requires a clear and immediate threat to oneself for justification.
