To me, that's a person of weak character

Isn't that rather a gross over-generalization? I'm not sure it's fair to characterize a person of 'weak character' for engaging in a fight, unless you know what the fight is about in the first place.

For instance, suppose you see a woman getting thumped about by her husband or boyfriend. Is it a sign of 'weak' character to wade in and attempt to stop it?

No, not a generalization at all. I DID know what every fight was about and since I was talking about myself, I'd say it's entirely fair.
Furthermore, that example you offered is EXTREMELY rare and you and I both know that 99% of fights are avoidable and certainly have absolutely nothing to do with protecting someone's honor. To imply that there's a hero factor that has to be calculated in is absurd and utterly dishonest.
