Who is the real hero

After giving a losing battle of carrom wid abhishek thot of refreshign myself by watching a movie. Searched the whole of many systems still found some sucking movies . But then suddenly i came across the VCDs of Zinda and thot of seeing the movie all over again . After watching the movie my mind has started racing again against the conventional thinking about the hero of the movie. No doubt both Sanjay Dutt and John Abraham had played their roles to perfection,they can be regarded as two hell of gud actors and the movie is worth watching but still I am not sure who is the actual hero of the movie. Is it Mr. Dutt or Mr. Abraham. All will say that Dutt jr. is the hero but i regard him as a villian in this movie. He did the wrong work which made lil reema chopra commit suicide and as any normal person (rather a heroic act) John took his revenge for his dead sister .And we all know the villain commits the crime while the hero saves the plot of the movie and is the charm of the scene and in this movie context, John is the hero . Isn't it ?
