I know all about the supposed “code of honor” some of these men hold dear; but wrong is wrong.
I can be a fantastic family man, chivalrous, and even give to the Church; but if I am a murderer - even if those murders are committed to earn money to provide for my wife and children - I have still broken a commandment and have committed a grave sin.
Even if I have my confession heard by a priest and receive God’s absolution; said absolution requires HONEST repentance and a SERIOUS commitment to try and NOT commit that same sin again. Otherwise how could God grant His absolution? How many of them are committed to not stealing and not murdering?
I don’t know how well you understand the Sacrament of Confession; but for it to be valid, there must be a desire and a commitment on the part of the penitent to change his life for the better. It is NOT NOT NOT a get-out-of-jail-free card.
