A more fundamental question is why morality - especially the kind that allows for violence against non-followers - exists at all. I hypothesize that morality was initially invented to subdue the masses into servitude - obey the alpha male, and slay those who do not. The logical next step would be to consider outsiders as disobedient to the alpha male until they accept his rule. Religions are essentially this principle, with supernatural being(s) as the ultimate alphas, and prophets as their messengers. Ideologies do away with supernatural beings, maybe replacing anthropomorphic gods with "forces of history", e.g. Dialectical Materialism or Manifest Destiny, and replace prophets with destined / enlightened rulers.
