I think she should be allowed home with her children as soon as possible.
She has made a mistake, and now realises it.
We would be a seriously inhumane and morally bankrupt country if it was decided that the nature of her mistake – support or ISIS meant she was not allowed to come home.
We all make mistakes, that is why they put bumpers on cars – and we should have a chance to put those mistakes right.
Add to that the simple fact that she will be someone from the Muslim community with first-hand experience of what ISIS is actually like, then her potential ability to prevent radicalisation makes her a valuable asset to our society.
