Dead penalty, worse that an entire life in jail?:
Depends. Both are given due to obvious and extreme criminal offenses. But then, I would really agree with you that death penalty is something that should be abolished. I dont know, I am not talking from the legal point of view, but on a moral level that no one has a right to take another persons life, if crime is committed the punishment should be ''corrective'' and something where the criminal should go through repent. 

Entire life in jail, made to rot in jail, or made to work, is better than putting someone to death.
