Religion and 9/11

First of all, I don't believe that now, after Jesus has come and left Earth, that God would want to kill sinners, as he knows that they can be forgiven anytime in their life if they want to be. Secondly the devil is the father of lies, and could imitate God's voice, telling people to kill. I don't believe that the devil would ask me to help somebody in my family, and even if he did, how would I know it was him and not God? I didn't answer the last question because I don't know whether the murderers were religious or not, but if they were I doubt that they are Christians. Yes they believed in God, but not the Christian God. Probably more than one God aswell.
