hurt a fly

Cause minimal damage

Hurt a fly appears almost exclusively in negative constructions: someone wouldn't hurt a fly, couldn't hurt a fly, wouldn't harm a fly.

The phrase emphasizes extreme gentleness or harmlessness—if someone wouldn't hurt even the most insignificant creature, they're incapable of violence or cruelty toward anyone.
