Tell people that what they don't want to do (be good, kind, charitable, etc.) is important all the time, and that what they do want to do (feel self-important and kill infidels) is okay in a very small number of situations, and you'll see a religion full of people feeling self-important and killing infidels, deriding those who are good, kind, and charitable for "not getting the point."

Tell people whatever you like. If you have left the killer ape the tiniest opening, it'll crawl right back in and plop itself in the throne of consciousness.
