#1: MUNTZ: (Up)
Muntz is best described as determined, paranoid, insane, selfish, greedy, violent, bitter, hateful, loathsome, charismatic, manipulative, traitorous, deceiving, angry, sly, men, cunning, ruthless, intelligent.

But really think about it.. He was an explorer who was accused faking the bird's discovery, and if didn't prove it too be real, there goes his career.. However.. He has 50 years in the jungle trying to catch the damn thing and now that he has, some kid and an old guy are trying to steal it back from him.. You can argue the bird had babies, but I don't think Muntz even knew about this.. He didn’t even plan on killing the thing. He just wanted to get back his respect from the scientific community. Sure it’s implied that he attacked the other people who he thought were trying to take his discovery from him, but we aren’t given any details, so for all we know he just chased them off with his cane..

#2: SID: (Toy Story)
Sid is not a true villain, being that he didn't realize that the toys are really alive when breaking them, but since this movie is in the point of view of toys, he can be considered an antagonist.

But keep in mind.. Maybe the toys could have let him know they were real when he first started getting abusive, instead of ganging up on him, and making him suddenly aware that all toys are alive, and leaving him MORE messed up..

#3: SHERE KAUN: (Jungle book)
Shere Khan hates humans which is COMPLETELY understandable. Humans are responsible for guns, fires, deforestation, and poaching. Aw, so sad he wants to kill a cute innocent wil baby human ... except he's really being proactive in protecting the jungle. He's got more logic than any other tiger attacking a human. Other animals fear him because he's a dominant predator, but hey, kids, that's the circle of life. It's more messed up to be friendly to your future prey (I'M LOOKIN' AT YOU, SIMBA).

#4: STINKY PETE: (Toy Story 2)
Sometimes it's tough to know what's in our own best interest. Placed in a situation and forced to make a decision, it's often better to ask for someone else's perspective. Like in Toy Story 2, when the "villainous" Stinky Pete explains to Woody the inevitability of his being forgotten by Andy.

Stinky Pete has firsthand experience with the harshness of reality, having been given away by the owner he used to love. So when he tells Woody their best fate would be for them to live forever in a museum in Japan, he means it.

Not only that, but he desperately wants to help his friend Jesse, too, who won't be accepted by the museum unless Woody accompanies her.

Stinky Pete might go too far in his attempts to change Woody's mind, but he's clearly been deeply hurt, and speaks candidly from a traumatic past. Pete needs help, nothing more - yet the toys treat him as if he's some sort of psychopath, refusing to ever concede that he's right - Andy will eventually forget them.

#5: SCAR: (lion King)
"It's the circle of life, Simba. You must respect every creature, from the crawling ant to the leaping antelope...except for the hyenas - screw the hyenas!"

This is basically what Mufasa means at the beginning of The Lion King when he talks about the circle of life. Sure, it sounds good in practice, but Mufasa is a bit of a hypocrite - he banished the hyenas so far from the rest of the savanna that they're literally starving. What did they do wrong? Were they eating lions? Isn't THAT the circle of life?

Which brings us to Scar - when Scar recruits the hyenas, he does so by promising food. Not only that, but we actually see him give them food, so it's not like it's an empty promise. Sure, he wants to be the leader of Pride Rock, but again - that's still the circle of life. Animals in the wild vie for power even between the same species.

I'm not saying Scar's a nice guy or anything, and this doesn't excuse the murder of Mufasa, or any of the other dick moves.. But at least at FIRST he seemed too to have "okay" intentions..
