ช่วยแปลประโยคนี้หน่อยครับ ไม่เข้าใจ

Whoever appeals to the law against his fellow man is either a fool or a coward
Whoever cannot take care of himself without that law is both
For a wounded man will shall say to his assailant
"If I live, I will kill you. If I die, you are forgiven"
Such is the rule of honor

Lamb of God – Omerta

สองบรรทัดแรกแปลว่าอะไร?
