It's not even close. You'd still be alone, and you'd still be angry. Anger is a poison. It's a cancer that's eating you up and destroying your happiness. If I killed that drunk driver, you might feel better for a moment, but it wouldn't last.
Angry people use blaming and justice like drug addicts use their favorite drug.
The effect always wears off, and they always need more. Justice and anger will never make you happy. You'll never find it in what you call justice. No matter how severely you punish that drunk driver, you will never feel that kind of happiness. If you really want to be happy, spend your time around people who can love you, and prepare yourself to love other people.
