I can say that he either wanted to poison his wive, or cause an abortion without approving or promoting either activity.
You said “Please convince me these rules are not really just rules in place to control women.” If it’s just poisoning, then I don’t see the relevance of your statement. But you pointed out the disparity between a doctor doing it and the husband doing something similar. I really don’t think you meant to say that a doctor might poison the woman. I know that because you said, “A DOCTOR who would be performing an abortion AT the patient's REQUEST....can receive a life time in prison.” So just be honest and state that you don’t think the husband should face a harsher judgment because he poisoned his wife, but because he tried to do what an abortion doctor would receive a harsh sentence for.
