You got the concept wrong, my brother. Islam is a religion of peace and high moral valures. It teaches one to hate sins not a person indeed. All the messengers on the eath baught the same message. One should not hate a human being but the evil/sin in him. if anyone wants to stay back with sin and harms a good human being then a good man has to protect himself. A good religiuos man always loves the humanity because it is devine creature of God. A person who kills someone on the name of God is a real fool and no religion teach this. Indirectly he dont follow any religion.
