Rebute the dictum - "An eye for eye makes the whole world blind"?

Question

Post the thoughts only against the saying - "An eye for eye makes the whole world blind"

Answer 1

Well, a good argument would be for capital punishment.  I believe capital punishment is the right thing to do.  

Why?  Because the risk is too high of letting the person live and possibly repeating their action against another innocent victim.
