can it be good to fight if nobody gets hurt and tu resolve some issues o is all fighting bad?

I don't see how tu can fight and not get hurt, it just doesn't compute to me. And it's all violence anyway, so yeah, it is morally wrong.

It isn't a "good" fight unless someone gets hurt. I think fighting is a good way to let stress out, and to stick up for yourelf.
To some people fighting is a hobby, it's just what they do. And when I say "fight" I don't mean that sissy slapping each other across the face kind of fighting I mean punches and bloody noses.
