So you made a worthless general statement that is in fact quite wrong, and does actual harm by preventing solutions to very real conflicts going on right now that are leading to the murders of thousands of good, innocent, people.

Evil exists because it's often quite successful. It has to be defeated by violence. If not for copious amounts of violence against Russia, their invasion of Ukraine would have been extremely profitable. If not for copious amounts of violence against Iran, they'd successfully wipe out Israel and achieve their goals of Islamic supremacy.

On a smaller scale, violence is a shortcut to success. The low IQ man that steals a purse or rapes a woman is stopped by violence against him. Yet, there's no fixing the fundamental problem: he's a stupid, worthless, person who has no place is society and would never achieve the success he wants without violence.

You have to accept bad people exist and stop them.
