After reading the trope page I question Broken Messiah
's tropability. In my opinion, this trope is a way to play with All-Loving Hero
Downplayed: They love most people but not everyone. (OR) They love their love interest more than they love everyone else
Deconstructed: In real life, everyone will, at some point in their life, find someone they dislike or commit a selfish act.
It could also be seen as a downplayed version of Fallen Hero
; not perfect but not truly "fallen".
Third, there is significant overlap with Break the Cutie
. Start off with an innocent and idealistic character who loves everyone and helps others etc and then discovers feelings of jealousty or hatred and is tormented by them.
