Wait a minute dude. Let's be more clear, don't over generalize them all.  On one side they go to churches, mosques, temples, and there are some who killing, cheating etc. Please be sure, are they the same people?\nI'm sure not all of them do both praying and killing. For those who have understanding to the meaning of praying and believe to God, i'm sure they won't do the bad. Please be sure also, that there are many who have no religion, no praying, no worshipping to registered Gods, but they do the peaceworks, decent people, with great love each other, etc.\n\nI just wanna tell you not to judge it over generalized, dont mix them up, or you'll be miss. The rest of your ideas is ok.
