Challenge regarding Christian morality

[Dystopia]

"An eye for an eye leaves everyone blind."
Unless, of course, you happened to be blind already, well, then, that's a rather awkward situation, isn't it?

So instead only the good people should be blind? I never really understood that one. Maybe if you didn't stab someone's eye out in the first place, we wouldn't be having this problem. Or am I missing something obvious here?

Instead we should find methods for less people to become blind. And that is not done by blinding those who blinded others. It is done trough research and application of studied political, economical and social measures. There's a reason the state with the highest probability of prisoner rehabilitation, Norway, has these 5 star ranking prisons and doesn't execute anyone.
