Most religions do have some philosophy regarding peace and non-violence. Some religions preach warfare for some reasons, others shun violence whatsoever. I shall list religions having violence as theme in decreasing order. 1. Islam 2. Christianity (though Christ never preached violence, his followers do) 3. Sikhism 4. Hinduism 5. Budhism & Jainism
