In Survival of the Fittest, Dorian, one of the terrorists behind the Act, has been shown to send most of the money he earns from working in the organisation behind SOTF to his mother. It helps that he's well... pathetic too.
In Suburban Knights, after spending the entire event tricking and manipulating the reviewers of his site, all while he himself refuses to play along and act in character and generally is a selfish bastard, the Critic is genuinely worried about Team 2 after he figures out that the map he got in a chain letter was sent by Malachite, and that Team 2 had no way of knowing that there was an Evil Luddite tracking them down. Immediately after, he and the rest of Team 1 band together to take down the next obstacle, so that they can quickly find Team 2 and warn them. (Given how the reviewers in general had their turns as jerks, this would count for them all in general)
Likewise despite everyone despising Mati and constantly sending him off on Snipe Hunt s to keep him out of their way, once he suddenly shows up while Malachite (a dark wizard who was beating all up them up rather badly) is there and starts yelling at him because he's frustrated with everyone else they all show serious concern for his well being and try to warn him to leave, instead of simply allowing Malachite to kill him without protest (which would get him out of their hair forever)
In There Will Be Brawl, Wario, the series' resident sneaky and manipulative bastard, is revealed to also be taking care of his mentally-handicapped brother, Waluigi.
Then blows all the acquired sympathy by using him to deliver a bomb to Red.
There's also a subversion when he apologizes to Red's girlfriend for causing Red's death, offering her money to make amends. As he walks towards her, the audience can see him holding a Home Run bat behind his back. Fortunately, Leaf is not fooled and kills him with Jigglypuff.
Despite all her abuse, The Nostalgia Chick's shown affection towards Nella on occasion. The end of her Ever After and My Little Pony reviews give the impression that she knows how ridiculously adorable Nella can be and loves it like the rest of us.
From the Global Guardians PBEM Universe, Diabolical Mastermind Lord Doom was one of the primary researchers behind the AIDS cure. He provided the cure to the world not for any underhanded ulterior motive, but because the AIDS epidemic was killing innocent people and he wouldn't stand for that. He also gives tens of millions of dollars to charities every year.
The entire SCP Foundation adores SCP-085, an animated drawing of a young woman named Cassy who has become aware of her medium and fallen into depression as a result. Considering most of the SCPF's actions toward sapient SCPs are... professionally detached, it's cute to learn that one of the first requests they had for a magical vending machine was "something Cassy will like" (it produced a cup with an illustrated milkshake on it, which Cassy said was "delicious").
"SCP-076-2 has however, shown that it has great knowledge of human anatomy (although in a highly violent context), military tactics of open warfare, metallurgy, and, strangely enough, the care of livestock."
In Shadowhunter Peril, Oblivion the single most powerful being in the entire story, and who can turn into something that resembles a near-Eldritch Abomination-type creature, enjoys murdering helpless civilians for fun, then stabs the entire resistance in the back by a attempting to kill Puriel and joins the enemy because he was bored of not being able to fight anybody. Word of God states that he has an unwaveringly fierce love for kittens.

Shizune, as Student Council President, has a reputation around Yamaku as incredibly bossy, and as a result, everyone besides her best friend and interpreter, Misha, left the council. However, in Hanako's route, she helps Hisao take Hanako to the nurse's office when she suffers a panic attack, and it's implied that she likes and is concerned about Hanako, but can't get close to her because Hanako's best friend is Lilly, who is in a feud with Shizune. In Lilly's route, Shizune manages to reconcile with Lilly. In Shizune's own route, she reveals that all of her actions, starting with her attempts to recruit Hisao to the student council, were done so that he would snap out of his depression. She also states that making people happy and engaged is her goal, and she hopes to become a philanthropist.

RWBY: In a textbook and somewhat literal example of the trope, not even WeissSchnee can resist the charms of Ruby and Yang's pet corgi, Zwei. She falls into childish babbling scant seconds after seeing him.
Weiss: "Oh, I'll miss you so much we're going to be best friends I can't wait to see you again gaga you're so cute [*unintelligible*]"
