ISIS exists because Islam has a jihadic tradition, and young, disenfranchised men are prone to violent actions. It's not like this is a problem specific to Islam - the Crusades were a similar exercise for christianity (where the Crusade wasn't an outright pirate raid https://en.wikipedia.org/wiki/Fourth_Crusade https://en.wikipedia.org/wiki/Fourth_Crusade), and China has historically had lots of rebellions when the population of angry young men gets activated.
