Given the nature of what we know about BG3 so far...since we are starting the game with a special, unique tadpole, allowing a player to play through the whole game and then, based on what the player wants, allowing them to give in fully, in cinematic fashion, to the tadpole and become a mind flayer would not be a bad ending. At that point the game is done, credits are about to role and it's strictly aesthetic. I plan on playing through the game from many different characters, perspective, and alignments and would honestly try to get that cinematic at the end on one playthrough.
