War crimes are serious violations of the laws of war that occur during armed conflicts. These can include acts like intentionally targeting civilians, using prohibited weapons, or committing torture. Such actions are not only unethical but also illegal under international law, and those responsible can be held accountable in courts like the International Criminal Court. The purpose of defining and prosecuting war crimes is to protect human rights and maintain some level of humanity even in times of war. By holding individuals accountable, the international community aims to deter future atrocities and promote justice for victims, ensuring that such horrors are not repeated.
