why do we kill each other in the name of god?

i know that every religion is saying that killing the people without a reason is the most bad things in the humans.every religion says that don't compell them in your religion.your duty is to convey your message about your religion and don't force them.. it is not justified that killing the innocent people in the name of god.every one was created by the almighty god.He has the right to give the life and kill the life of any person He likes.so,killing the innocent people in the name of god is not a justified one and i really condemn on this one...
