Why do many people think it's alpha and strength to get carried away by emotions?

For example many people criticize if you walk away from someone that betray or hurt you.

Some take revenge. Some would trash a cheater's car or fight the other person or assault both of them. They think that's alpha and strength but honestly I see that as weakness. You're weak because you're still letting your emotions dictate you. That's actually the opposite of being an alpha.

The person that walks away and doesn't make up any scene Is actually the strong person, the true alpha.

So it's like many people have it backwards. Reacting and going nuclear revenge Is actually not an alpha, never was.
Beta is walking away. Actually Is the opposite. Alpha is walking away.
