There are plenty of things that deliver the above without the dogmatic slaughter of hundreds of millions of humans throughout history and at this very moment.
There's also plenty of religious people who have never murdered anyone in their lives, and there have been plenty of dogmatic massacres for reasons entirely unrelated to religion. The two issues seem to be quite uncorrelated tbh.
Religion requires belief without evidence. (Or flimsy evidence like ancient testimony.) It's uniquely positioned as a tool to manipulate people to do things they wouldn't otherwise do.
