Cutting off the nose to spite the face
From Wikipedia, the free encyclopedia

Cutting off the nose to spite the face is an expression used to describe a needlessly spiteful or self-destructive overreaction to a problem. "Don't cut off your nose to spite your face" is a warning not to act out of pique or pursue revenge in such a way as to damage yourself more than the object of your anger.
