Eye for an Eye

I'm playing around with idioms and phrases a lot in this poem.

They say an eye for an eye leaves the whole world blind
And in a mad world the sane mans wits are resigned                                  
It's no wonder then, that out of sight is out of mind
An eye for an eye is a lie
Pound for pound, it's just trading pride for pride

A snake hissing threats at the roots of wisdom's tree and its fruit 
But wisdom and pride are like whisky and wine
Hard to swallow and leaves you red in the face                                      
Pride is an acquired taste
And as grapes from the vine, wisdom ages like wine
Revenge is a dish that ages like brine

Taking his sight for yours, and its prize?
You're the man with no eyes, but his pride!
They say an eye for an eye leaves the whole world blind
So the king in the land of the blind is the man with one eye
