The Canadian justice system is based on finding the balance between justice and rehabilitation. I think it's important to remember that. But regardless, I don't think either will be served by 'making sure his sentence isn't harsh', given the crimes he committed. There are appeals and parole systems for a reason. Give him a sentence that gives his daughter some justice, and let him earn his way to early parole via rehabilitation if he can. Being a rehabilitation system doesn't mean we have to let this guy off lighter than other violent rapists, just because he was 'good' enough to keep it in the family.
