Midori Rule
The Midori Rule (named after Sou Hiyori, or Midori, from the hit game Your Turn To Die) is a policy applying to fictional characters, where if you find them physically attractive but they're personality is disgusting or they've done something unforgivable. The rule dictates that said character can hit it once, and then you will kill them.

Person B: but they're attractive..
Person A: Yeah but they're a piece of shit
Person B: I plead the Midori Rule
