Go and attack the Amalekites! Destroy them and all their possessions. Don’t have any pity. Kill their men, women, children, and even their babies. Slaughter their cattle, sheep, camels, and donkeys.” God asks Saul to destroy a people, he didn't have the guts and let the women and kids go, guess what? He lost his kingship. I have a thousand more examples of things like this, God praising attempted genocide and commanding it. All in the bible. Now let me educate you, most laws commanding Muslims to kill appeal to wartime or jihad. Jihad can only be called on by a caliph or a very very high up religious leader. This has not happened once in modern history. As such Isis and any terrorist organization is an insolent and rouge group. They are over a billion Muslims, if the religion and not the bastardization of it was the problem the world would be a LOT more chaotic.
