I have a problem with how stupid the whole thing is with using the tadpole. Even Lord Voldemort, with how psychotic and power hungry he was, had enough sense to learn how Hocruxes worked, before he started splitting his soul into 7 different pieces. Our character can't even express an interest in learning how to control it like Astarion, and our overall goal remains to find a healer to remove it. Right now, everything associated with the evil playthrough feels like it was thrown in there because somebody over at Larian said they had to, but no one actually wants to make it satisfying.
