The reason why state after state and country after country abolish the death penalty is for the same reason they legalize abortion. Justice has nothing to do with it.

Timothy McVeigh admitted his guilt, showed no remorse, and therefore the penalty was not unjustly inflicted. Assuming that the guilty party's identity and responsibility have been fully determined, the traditional teaching of the Church does not exclude recourse to the death penalty.  His act  killed 168 people and injured more than 680 others, crippling several permanently.

The dead included three pregnant women, 19 children, of whom 15 were in the America’s Kids Day Care Center, ranging in age from three months.

I strongly suggest a visit to the memorial to view the pictures of the deceased.

His was a just punishment.
