I agree, I think the evil playthrough is really half baked and we should have more options like taking leadership of the goblins or demonstrating the absolute as a false God to Minthara. Even for evil stuff in CRPGs it's incredibly brutal and simply not a choice most people will pick. To me it's a lot like in PST
putting Morte back in the pillar

it certainly is an option, and options to do bad things should exist in CRPGs however the evil path in BG3 has so little motivation, logic, or reason. It only makes sense for a player who really really wants to murder children and druids.
