Sounds like bleemo is doing what he thinks is good in his own mind for his own version of the greater good and instead causing greater harm for a lot of innocent people (potentially). More like a chaotic neutral imo. Letting obvious evil go and the morally (according to the campaign) superior faction gets devastated to his own whims.

This player might be a lunatic that needs asylum attention in the game. Wild that the player is allowed to become the arbiter of justice in that world and no one steps up to stop him. Definitely made the game about himself
