What concept describes a person’s justification in using force against another when necessary for self-protection?

The concept that describes a person’s justification in using force against another when necessary for self-protection is self-defense. This principle allows individuals to defend themselves from perceived imminent harm, provided that the level of force used is proportional to the threat faced. Self-defense is rooted in the legal idea that individuals have the right to protect themselves from injury or death.

For instance, if someone is physically attacked, they may respond with reasonable force to prevent further harm to themselves. The legality of self-defense hinges on the context of the situation, including whether the threat was immediate and if the response was appropriate in relation to the level of danger presented.

In contrast, other terms like deadly force specifically refer to the use of force that is likely to cause permanent injury or death, which may not be justifiable in all circumstances. Reasonable means could suggest acceptable strategies or methods for protection but lacks the clarity and legal standing that self-defense carries in justifying the use of force.
