Why do you want to murder your husband? Because it is very difficult for a woman to kill her husband, even if she fights alone, unless the man is ill and can't move.
It is very simple for a man to kill his wife. Men have great strength.
Another important reason is that men are superior to women. In the past, women paid attention to marrying a chicken and following a dog. No matter what her husband looks like, they have to endure it from beginning to end. They can't complain at all, let alone kill him. This is a shameful thing for others.
