I think if both parties are willing participants then fighting is fine.

I also think that in many fights, what one person does is very wrong while what the other person does is very right.

And some fights are just wrong.

Is that a vague enough answer?

The 2nd sentence confuses me

Its simple, in many fights there are two people.

I think, in many fights, one of those people is doing something wrong, and one person is doing something right.

Attacking someone for a stupid reason is wrong. Defending yourself is right, and defending someone who cannot defend themselves is even more right.

Make sense?

Yeah. And i guess i did the very right thing then.

Good job then.
