A character who has murdered hundreds of people and can possibly kill you with his hands but his/her fans (fangirls) think of them as the sweetest person alive and will protect them at all costs
Eg:

Girl 1: I just love Loki and Bucky and what happened with them was wrong.

Girl 2: But they killed so many people
Girl 1: I know, Loki and Bucky are my murder muffins
