Ya cares for her by taking her to a place that will be a mild form of torture between pain from the water on her wounds and having to expose her bruised body to others assuming she is even able to go into the baths at all. Sounds more like he is going to a hot spring and just bringing her along for sex and to probably serve him.
Well, it's certainly clear that he doesn't know or doesn't care how this will affect her. As said, nothing he does, whether out of genuine care or only to seem like that, will excuse the, as far as we can tell, far more common abuse. It's a slight ray of hope she sees that keeps her with him, but I do hope she'll realize it's not enough before it's too late. I really have trouble finding the correct words here, so I apologize if I might seem to make excuses for him, that was certainly not my intention.
