Pssh. Scar? How about a REAL villain?
Let's see... what did Scar do? Well, he attempts to kill his nephew via underlings, commits fratricide with major help from underlings, drives off his nephew via underlings, somehow get the land devastated due to ineptitude, grumbles when people call him out on his inepitude, cowers to Simba when his rule starts crumbling, resorts to dirty tactics in his final battle and still loses, and gets eaten by his underlings after trying to pass off the blame to them.
So yeah... aside from underling management and one timely shove, what exactly did he DO?
Percival C. McLeach, now? Well, he's been poaching for years (long enough to become a wanted man), caused the death of an endangered species eagle, threatens his goanna partner with death multiple times, kidnaps a young boy, deceives authorities into believing crocs had eaten him, tortures said boy for information, tricks him into leading him to the endangered eagle's mate, captures said eagle with some kind of military-grade net missile fired from his (for lack of a better term) tank, sends his goanna to consume the endangered eagle's eggs for no reason other than being a douche, attempts to actually feed the kid to crocs (including shooting the rope holding the kid over the crocs) in order to tie up loose ends, beats away multiple crocs with his rifle after being knocked into the water himself, and ultimately falls to his (presumed) death over a waterfall immediately afterwards.
Now THAT is a villain!
(Criminally underrated, "Rescuers Down Under" is.)
