Even if your argument was true (which it is not), from it you can only argue that religion is useful. The ONLY important question with regards to religion is whether it is true or not, so what do you acheive by taking this approach to theism?
To your argument, you are wrong. Bad men do bad things, good men do good things. Give a man religion whether good or bad he can content himself on doing gods work whatever carnage there maybe. And no the religious don't just kill 'heathens'; muslims kill muslims for not being islamic enough, christians kill christians for being the wrong type of christian and of course they all kill each other. The problem for the theist is that there is an intellectual path from religion to a death cult (to satisfy the scarifices called for by the blood thirsty diety; just read the texts!); there is no such intellectual path for atheism, despite the horrors of the 20th century, regimes have not killed people becuase they atheism motivated them to do so, the same is not true of theism. The truth is people who want to do bad things use an excuse be it religion, or something else like eugenics; but give them religion and they can be proud of their actions in doing gods work.
