What is defined as the act of defending oneself or others using force?

The correct answer, self-defense, is defined as the right to use reasonable force to protect oneself or others from imminent harm. This legal principle allows individuals to defend themselves against immediate threats of violence, ensuring they can respond to aggression in a manner that is proportionate to the threat faced. Self-defense can involve various levels of force, depending on the situation and the severity of the attack.

In various legal frameworks, self-defense is recognized as a justified response when an individual believes that there is an immediate danger, and the force used to defend must typically be reasonable and necessary. This right is a fundamental aspect of personal safety and is essential in legal contexts regarding the use of force.

The other options do not specifically encapsulate the concept of defending oneself or others. Force regression, incapacitation, and threat neutralization may involve the use of force, but they do not specifically refer to the justification of using force for personal defense in the context of imminent danger. Therefore, self-defense is the most accurate and recognized term for the act of using force to protect oneself or others.
