Student said controversial things

I try to avoid politics as much as I can when I teach. If I get comfortable with someone, I get into it. I won’t say the specifics, but one student basically hand waved the death of children to me. I have taught this person 4 times and they have a few more lessons that they purchased.

Now, they didn’t advocate for the death of children, but they basically said “it’s something that needs to be done”. It’s sad that you can probably guess their nationality.

Anyways, although this person has been very pleasant, and I can avoid politics, morally, I don’t know if I can accept this. What are my options here? They already bought lessons.
