Video Game Cruelty Potential/Anime and Manga

Digimon Adventure 02 has a villain who takes this to the extreme; it's quite clearly implied that he treats Digimon absolutely horribly... however, we then learn that he was under the impression that the Digital World was a video game all along.
- When confronted to the fact that it's real with no more possibility of escape or denial, he completely breaks down and later joins the good guys.
  - Before the series started, he had his own Digimon adventure, which resulted in him getting brainwashed. But that ties into several awesome video games that were never released in the USA.
This happened again in Digimon Xros Wars. This time, Yuu Amano was manipulated by the villains into thinking the digital world was just a game world where he could play however he wished. All he wanted was a way to play to the best of his abilities without the risk of anyone getting hurt, and when he finds out this isn't the case- and that a lot of death and destruction has come from it; he also has a major breakdown. Fortunately, the heroes, one of whom is his loving sister, are more than willing to forgive him and help him come to terms with things.
