Evil's Gotta Evil

''Evil's motivation < good's motivation. Fight us.''

When evil is doing things that hurt people without any given reason, it's likely only because Evil's Gotta Evil. This is the explanation that makeshift antagonistic roles and SMCE Villains have for messing everyone's day up without any scheme, not even easy go-tos like World Domination or Kill The World Because Lol. Non-adventurous antagonists like Bullies and Adversaries have a similar UnTrash that fits them: Rudeness Is Rude.
