Why these killings?

This space is open to all muslims who are willing to explain why it is necessary to kill innocent, unarmed people. Of course, I do understand that from a muslim perspective those killed are not in fact innocent. They are infidels. And therefore they must die. The killers, on the other hand, are muslim heros. They must also die, apparently. 

Our children want to know why a religion that calls for so much killing is a good religion. 

If there are any muslims wishing to express regret for what happened in Paris on Nov 13, 2015, they can do it here. I welcome every single one.
