Frozen. Hans has a tiny, tiny one. When his horse accidentally knocks him off the pier and into the sea, instead of getting annoyed, he smiles at it.
Averted in The Hunchback of Notre Dame. Frollo sparing Quasimodo's life in the prologue and raising him might have been an act of kindness for an otherwise wicked person and even become a redeeming factor if his reasoning wasn't screwed up in the first place and he did right by it. Frollo twists it around for the following reasons. First off, he only does it after the Archdeacon tells him to. Second, he does it simply because he fears God may punish him for his sins. Third, he refuses to allow Quasi into his household, and exiles him to the belltower for the rest of his life. Fourth, he simply sees Quasi as a pawn he may use later on, and never truly accepts him as his son. Fifth, he lies about the death of Quasi's mother instead of revealing the truth when Quasi's ready that he raised him to atone for her death. Sixth, he's completely emotionally abusive towards Quasi, drilling it into his head that he's just a monster whom no one but him could "love".
The Lorax. Exploited: during the Once-ler's Villain Song "How Bad Can I Be", he sings: "Just look at me petting this puppy."
In The Princess and the Pea, Helsa isn't exactly a good person, but she did have second thoughts when Laird wanted to switch their newborn daughter with their niece as part of his revenge, and she made him promise not to harm her.
Similarly, Maleficent of Sleeping Beauty cared quite a bit for her raven familiar Diablo, literally stroking him at least a few times. She's also quite horrified and saddened when he's Taken for Granite.
A more heroic example - throughout the beginning of Tangled, Flynn steals a tiara from the royal family (one which is so highly valued because it belonged to the king and queen's kidnapped daughter, no less), betrays and abandons his partners in crime to keep it for himself, and constantly tries to weasel out of his deal with Rapunzel, which leads to him taking her into a bar full of thugs to try to scare her into going home. When the thugs find out that he's got a bounty on his head and trap the pair in the bar though, Flynn shields Rapunzel from them.
In Wreck-It Ralph, that Ralph is merely a bad guy, not a bad person, is shown when he shares his stolen cherries with orphaned characters.
