What does self-defence allow an individual to do?

Self-defence is a legal principle that allows an individual to protect themselves from harm. It is crucial that the force used in self-defence is proportionate and reasonable in relation to the threat faced. This means that when someone is under threat, they are allowed to use a level of force that is necessary to protect themselves, but it must not exceed what is considered reasonable given the circumstances.

For example, if a person is confronted with aggressive behavior that puts them at risk of physical harm, they can respond with reasonable force to neutralize that threat without escalating the situation unnecessarily. This aligns with the legal standards that govern self-defence, ensuring that while individuals have the right to protect themselves, this right is balanced with the need to avoid excessive force.

In contrast to the other choices, which propose either excessive or inappropriate responses, the acknowledgment that self-defence permits reasonable force to defend oneself is critical. Using any force necessary to protect others could lead to situations where innocent people may be harmed, while engaging in preemptive attacks or escalating conflict undermines the principle of self-defence by promoting aggression rather than protection.
