Yesterday night I was jumped?

The guy tried taking my iPhone but fortunately I was able to fight back, he punched me several times and made my nose bleed, but i was able to overpower him but I didn't want hurt him. My friend says that if he were me he would have broken his bones. Is this because I care too much?

Well I would try to hurt back someone who is attavking me and stealing my property. If he attavked you, hit you, you had all right to hit him back.
