Hammurabi’s code was not just because it was not fair to everyone in a criminal situation. Everybody knew there were consequences for their actions. If a person is about to die, and the doctor is trying to help, but the person still dies - the doctor is punished by having his hands cut off. Law 196 says, “If a man has knocked an eye of a free man, his eye shall be knocked out”. Then Law 199 says, “If he has knocked out the eye of a slave, then he shall pay half his value”. This is not far to the slave because he is a man just like the “free” man. Also Law 48, talks about how if a creditor gives a man money for his crops, but a flood prevents the crops from growing, the creditor does not get his money back.
The code was supposed to protect.
