Is this a greater evil - someone who proclaims himself to be a follower of a faith and yet merely exists to be one because he feigns so, through his actions and false words uttered; or even perhaps he was conferred no choice and had to fake his belief?

Or would this be a greater evil - someone who claims to have no faith and yet treats beings with kindness and respect and lives a virtuous life that, in all aspects (other than religion of course), is worth modeling after?
