What if part of Asterion's healing in the love route the Master and Asterion speculate on how bad it could of been had the master chosen to be abusive. This would allow for the player to do the bad route and not feel bad about it. Say the entire time the Master is uncomfortable making the bad choices in the hypothetical scenario but Asterion encourages the Master saying things like "this is the exact opposite of what you do", "I need to know how you wouldn't act", "I need to expose myself to my greatest fear to get over it", "I want to see how bad it really could of been to know how good I have it instead", etc. also despite not liking the idea I guess in the bad routes the same speculation could be used to enhance Asterion's suffering showing him how good he could have had it but wont, maybe in one of the bad routes the Master does feel some degree of regret and maybe even kills himself out of shame and regret for what could of been. (I still havnt played any of the bad routes so I dont know if this would even apply)
