Basically not being egotistical is what most are talking about.
My reason if I ever come to conflict with let's say a mugger, we have many cases like that in Indonesia, not quite a safe place, yes, I would not run and stand my ground. But, I have a few reasons for doing this, not because of pride:
1. If I just give the mugger the wallet, than the mugger would be satisfied that intimidation works and will keep doing it to others.
2. Whatever the reason is, mugging is wrong, the mugger must be taught of the mugger's wrongful ways.
3. Is there any guarantee, if I give the wallet that the mugger will let me live?
These reasons are actually caring for others, the person that is attacking you, and for one's own life. Would this be wrong?
I walked away from evil thoughts when a bus sideswiped my car (don't talk about legal issues here in Indonesia), scratched my back tire cover. I could just easily beat the crap out him to teach him a lesson. But picking fights over a scratch on the car, that is silly and stupid, and just egotistical. If I carry on further, I would probably make a fool of myself, create further traffic jams (which was already bad enough at the time), and in the end, the bus driver wouldn't have learned a thing (they are that lowly educated here). So I walked away in the best interest of others and myself, and I felt sorry for the bus driver, because he didn't learn a thing. Walking away in this matter was the best solution.
