Tbh, the concept doesn’t require a specific religion or even any religion at all to work.
Christians can do that, so can Jews, Muslims, Hindi or any other religion. Or Marxists or Capitalists, Nazis or Brits, Americans or Russians.
In general, large organisations (countries, companies, religions, …) that want to gain money/power through violence usually pick a random ideology or motive to do so, because it helps to justify the act and thus motivates soldiers/fighters and potential recruits.
But the justification is never the actual reason. The reason is to increase money and power.
