I am sure there is an English expression or idiom saying that a person puts his anger on an innocent person who didn't cause it. But, I can not remember it.
Say, a husband had an argument with his wife. He was so angry that he screamed at his children even though his children didn't have anything to do with his anger.
In Vietnamese, we say "hate the fish, chop the cutting board" literally translated. It means you hate the fish but you can not express your anger at the fish so you chop the cutting board to vent your anger.
