Weapons that cause unnecessary suffering are categorized as what?

Weapons that cause unnecessary suffering are categorized as illegal because international humanitarian law, particularly the laws of armed conflict, seeks to limit the effects of armed conflict for humanitarian reasons. This body of law emphasizes the distinction between combatants and non-combatants and prohibits the use of weapons that inflict excessive injury or suffering on individuals who are not participating in hostilities.

The concept of unnecessary suffering is rooted in treaties such as the Geneva Conventions and their Additional Protocols, which outline acceptable means and methods of warfare. These laws are designed to protect those who are not actively engaged in combat, including civilians and wounded soldiers. Therefore, weapons that cause undue harm or suffering are deemed illegal under these international regulations.
