My example: Tighten from Megamind and Elliot Rodger.
Both were down on their luck underdogs who have been rejected by women causing them to turn violent and aggressive. They were both narcissistic and entitled, believing that women owned them their affection, they refused to look of what was inside of them that made them be rejected in the first place as they already saw themselves as the good guy, they blamed every else for their misdeeds when in reality they brought their misery on themselves. When they let out their anger, they caused destruction wherever they'd go.
