Law 129 If a married lady is caught with another man they shall bind them and cast them in to the water.I think its just because they can both die at the same time and the mans wife can be happy that they deserve that.
Law 148 If a man has married a wife and disease has seized her if he is determined to marry a second wife. I think its just because the the sick wife will get more time with her husband and the mans girlfriend will get sad and she wont get more time with him.
Law 195 If a son has struck his father his hands shall be cut off. Its not just because they can do something else to him cause its way to pain fool and to bloody.
