This has nothing to do with religion, colour, race, political beliefs that is just an excuse used to justify what they have done. I have dealt with all sorts over 30 odd years the thing I found that they have in common was the need/ability to kill to get their way or what they want. I might add the few that go out from prison and lead a good life never to be heard of for the wrong reasons have my admiration as the odds are stacked against them.
