Challenge regarding Christian morality

[Huggy Bear]

What do you think justice is? What is your definition?

Justice is essentially fair punishment, hence an eye for an eye.

A maniac kills a child. He is a married breadwinner. He is caught beyond a shadow of a doubt. His family are good people.

Throw the maniac in jail and the family suffers.

Execute the man, the family suffers.

Justice is impartial to all that, it just seeks to bring the scales back into balance, which is why it's depicted as blindfolded and holding scales. Those are consequences the man should of thought about before he decided to murder some one.

As the child is already dead, the only way to avoid adding to the suffering is to leave the maniac alone.

Where is the justice?

Surely you can't be suggesting that murderers go unpunished....
