We have an ISIS bride story in the UK as well.
Your ISIS bride is penitent. Ours less so. Yours is 25. Ours 19. 19 is still very young.
It is hard to know how to treat them. I'd probably bring them both home. But we need to figure how to deal with them if they do return. You can't feel free to join a terrorist organisation and there be no consequences.
Also, British people were beheaded by ISIS monsters. Their family's interests also matter.
Very hard problem.
