It doesn’t matter if they aren’t Christ-like. Many, many Christians, including clergy and even pontiffs have committed atrocities. They still worshiped Christ, making them Christians.
If we were to play it your way, the Crusaders weren’t Christians, the Spanish Inquisition weren’t Christians, the Conquistadors weren’t Christians, etc. I don’t think that’s what you intend, but that is the problem with suggesting people who are not Christlike are not Christians.
Otherwise, we need to invent a new religion and put a huge percentage of people from the last 2000 years who thought they were called Christians into it.
