And which religion says everyone who isn't "saved" is going to hell when they die, where they'll they burn in agony for all eternity, including unbaptized babies?  How many Christianity based cults have committed mass suicide? As for "Christian cults" claiming the lives of thousands in self-described terror attacked:  again, I refer you to the Crusades where an estimated 200,000 perished.
"The crusade was a long drawn war which lasted for over 200 years. Can we then fathom the bloodiness of the war and the number of people who died? The anticlimax in this war was that it had the sanction of the Pope. The novelty of war otherwise would be to defend one’s territory or self-defense. In the crusade not only did the blood-shed get justified, it was also called ‘just’ and the crusaders were reassured forgiveness for their sins and a place in heaven in the event of death in war."
