There not killing in the name of religion because no religion or God would except what there doing its all to do with power

No, unfortunately, it is very much motivated by religion; everything they do is explicitly justified word for word in the mad, self-contradictory scriptures they follow.  There's a reason why they tearfully hug gay people before throwing them off buildings and victims of rape before they stone them to death: because they honestly believe that they're delivering their victims from a life of sin to divine forgiveness.

We'd like to believe that it's all about power for them, because to us that seems more sane and rational.  It's the kind of evil we can accept as being evil.  We struggle to cope with the fundamental concept that in the twenty-first century, people would actually genuinely believe they can create a utopia through murder and that such a project would be divinely blessed.  Maybe that's to our credit as a society; we are, apart from a few rum buggers here and there, a pretty decent bunch.  But if we ignore the fact that it's happened in every century of human history to date in the name of one cause or another, and is now happening again on our watch, then we're going to make this a thousand times harder to deal with.

Also, I wouldn't worry too much about numbers.  Most people of all religions are pretty decent types, just trying to do the right things (and, in the process, merrily ignoring the bits of their holy books which tell them to chop, maim, gouge and sow the earth with the blood of the unbelievers).  People in general have got a lot in common, and that will always be the key to defeating maniacs
