This doctors 'religion' has been murdering one another for centuries, in fact, the Christian Crusades were in response to Muslim warriors trying to take over Jerusalem. 

This 'cult' has been at the center of nearly every inhuman activity since 2000 years ago, they pray to a warrior, they all have similar ides of 'right and wrong' and Wrong is the side they all come down on.  From warriors to terrorists, it's been going on for thousands of years and will continue, for nothing has changed in their medieval cult for as long.
