Abstract
Considering that unjust combatants do not have the same rights as the just combatants, I will analyze whether motivation plays a crucial role in the moral responsibility of unjust combatants. ‘The motivations’ mean the moral reasons for acceding of combatants to war. I will examine the motivations of soldiers and their influence on moral responsibility and indicate whether this has effect on the unjust combatants’ justification. I would like to underline the connection between neurobiology and ethics which can help to look at this problem from a different perspective1. Keywords: Motivation, Belief, Combatants, McMahan, Moral Responsibility, Justification.
