Not really comparable. Organized religions have been certainly guilty of some pretty harsh things. And so has government. I don’t have a body count, to be honest with you.. but Vietnam, China, the Soviet Union,and Nazi Germany during the 20th century certainly killed millions upon millions of innocent world citizens.
I guess government killed too.. but I’d be more inclined to believe that through history the ‘state’ killed due to religion much more than the religion itself.
