I think mostly all religions are guilty of doing some bad things in the name of religion including those who profess to be Christians. In fact this was mentioned in the Bible Book of Revelation 18:24

24 Yes, in her was found the blood of prophets and of holy ones+ and of all those who have been slaughtered on the earth.”

Now noticed i said most religions the reason i said that because there is a religion that pratices the two greatest Commandments which is number one love for God and two love for neighbor so in other words they refuse to fight against tgeir fellow humans even if this means persecution or jail.
