religion doesnt contribute to wars from the "wisdom" imo... tht requires a human interpritation, and not from the religion. Just as the good comes from human interpritation... Religion, as any source of wisdom, is a tool. That tool and wise words can be twisted to any means youd like.
Its like poetry, one can say it inspires love, and romance, and compassion and all sorts of good things. But one can interprit those same words to mean bad things too.
