Ok... so exactly what is your criticism? Sounds to me like all the depraved activities you listed ( beaten, maimed, enslaved, raped, and slaughtered) are just different aspects of the ultimate perverted sex and death cult. I suppose it could be called the RT&M (rape, torture and murder) cult if that makes you happy....
I don't know how many people have died from engaging in S&M, or whatever you want to call it, sexual activities. Followers of Islam have murder hundreds of millions in the most horrible ways imaginable:
