YMMV / Mortal Kombat vs Marvel Universe

• Moral Event Horizon: Raiden crosses it by ordering the genocide of Chaosrealm and having Vera Briggs raped, tortured and killed off by Kano and his son Darren. And if that wasn't worse, he slaughtered Nitara and her fellow vampires, reduced Z'Unkarrah (Outworld's capital) to a smoking crater (thanks to a nuclear strike), destroyed the Edenian and Seidan resistance forces, killed Bo' Rai Cho and had Fujin tortured to near-death.
  • Sure, Kano has troubled Sonya and Cassie in the past, but he and his son Darren cross the Moral Event Horizon when they gloat about how they took turns raping and torturing Vera Briggs before killing her. Sonya and Cassie do not take this lightly and both mother and daughter kill off both men for what they did to Vera.
