RE: Do You Limit Your Action and Behavior In A Fight?

There can be terrible outcomes when people aren't careful and don't limit the violence of their attacks.

Completely agree with that. That's why always use reasonable force to make any move. You don't need to hurt someone pretty bad if that's not necessary to defend yourself. If you can get out of there without any fight, that's always better. Unfortunately, when people get angry, it is difficult to think clearly at that moment, so there is a chance of making mistakes. And that can increase the violence.

When other people see such fights, they can at least call the police instead of doing nothing.
