I can see asking why someone abducted or abused doesn't reach out for help. I think what is being done in this case though is asking with ... "attitude."
I always remind people to read the Steven Stayner story. He was 7 when he was abducted, stayed with his abuser for 7 years. He was even enrolled in public schools as they moved around.
Understanding the psychology behind someone behaving that way is an acceptable pursuit, such as "I wonder what happened that he was unable to ask for help even when it was available."
Excellent Article for those who really want to learn, why.
