Guilt-Ridden Good People

Here's a question I recently got from a client. I've made all the details as vague as possible for privacy purposes. QUESTION:  My sibling and their spouse have been accused of abusive behaviour, and they have several kids who are now facing foster care. My family can't take all of them on, realistically, only a certain number of them. The others have been assigned Muslim foster parents. I feel very guilty about the kids we can't take on ourselves. What should I do?
