You ever think about how Remus, the personification of every thought C!Thomas deems unacceptable, would cease to exist as a concept if he was ever trully accepted?
Cuz if it ever got to a point where Thomas doesnt see everything he says as inherently wrong and bad then he would no longer be intrusive thoughts or 'bad imagination', he would just be creativity. Any part of him that becomes acceptable would automatically be given to Roman until there isnt enough substance left to make a whole side.
Remus inherently has motivation to never be redeemed by the light sides, because any attempt to do so goes against the very essence of what he is.
