15 Characters Who Will Probably Die In 2017's Biggest Movies

Why He Should Die

This might be controversial since Loki has already "died" once having seemingly learned the lessons of moral goodness and self-awareness (in Thor: The Dark World), but he then went and undid all of his good work by stealing his adoptive father's throne and pretending to be him.

There's very much a suggestion that he's aligned with the bad guys to begin with in Thor: Ragnarok, but he definitely switches sides, and with Marvel presumably not wanting to over-rely on Loki's appeal (he surely can't be in EVERY Thor movie, can he?!) and his new-found awareness needs to be cemented with death.

How He'll Die

It would be fitting for him to actually follow through on his attempt to sacrifice himself to save Thor last time out, particularly as his theft of Odin's throne seems directly to be a cause of Ragnarok and Hela's rise. Surely he has to be held accountable, and the only penance that would fit would be his death.
