What principle prevents unnecessary suffering or injury during conflict?

The principle that prevents unnecessary suffering or injury during conflict is rooted in the concept of humanity. This principle emphasizes the need to treat all individuals with dignity, regardless of their status as combatants or non-combatants. It is aligned with humanitarian laws and norms that seek to limit the effects of armed conflict, ensuring that those who are not participating in hostilities—such as civilians or captured soldiers—are protected from harm.

Humanity ensures that the means and methods of warfare are controlled, with the objective of protecting human life and dignity. It also calls for the humane treatment of all individuals, highlighting the moral obligation of warring parties to avoid actions that would inflict excessive suffering or injury.

Other concepts, while important in the context of armed conflict, serve different purposes. For instance, the principle of distinction focuses on the necessity to differentiate between military targets and civilian objects, while military necessity refers to the requirement that any military action taken must be necessary for achieving a legitimate military aim. Honor typically pertains to the conduct and ethical behavior expected of combatants, but does not specifically address the prevention of unnecessary suffering in the same way humanity does.
