* Gretel's bullying of Jacques during the first Tournament in ''RolePlay/YuGiOhEastAcademy''. This act is so cruel it actually [[BerserkButton prompts]] [[TheStoic Marcus]] to try and ''MindRape'' her.
** David firting with Crystal. Seems harmless enough, untill you consider that [[spoiler: Crystal had just lost her only remaining family member]] and that David was only doing it to amuse himself, rather than being genuinely interested in her... dick move, mate. ''Dick. Move.''
** Haine's [[spoiler: ColdBloodedTorture of Marcus and Sylvestre (which included outright ''murdering'' the latter.)]] Easily twisted enough to catapult Haine over the MoralEventHorizon.
* Rotor had a quite a few of these for a good guy in ''Roleplay/DinoAttackRPG''. Among such moments are arresting an ''entire T-1 crew'' because the pilot disobeyed orders and then trying to have them all shot, ordering Kate (an innocent and inexperienced teenager) to enter a fortress filled with toxins on her own and berating her for crying, and [[ColdBloodedTorture beating a pair of prisoners (including a young girl) during what was supposed to be an interrogation]]. Rather noticeably, once he started cleaning up his act, he stopped Kicking The Dog.
