Actually, (spoilers!) that is part of it! He does die in the cold, you have to get the other ending to find out. I won't spoil it too much incase you wanna play that ending for yourself, but all you have to do is make sure that he DOESN'T get to 1M subs, so just tell him to hide his goal from his followers and not sing the karaoke stream. Then you should be all set ^^
