Yes, if you think about the fandom in all of it, plus the storyline, Mufasa was more the jerk at first, and Scar just turned into one through jealousy.
True, but at the same time you have to feel sort of bad for him. I mean, how would you feel if you were there while your parents picked a sibling over you? To me, it is a mixture between: "That jerk!" and "Aww. :c"
from Mufasa's POV, he's a psychopath. But from Scar's POV. he kinda deserved it.
