“Do you want to follow Christ, or do you want to be a Muslim?”
If you’re a Christian captive of Boko Haram, the Nigerian terrorist group, the path to staying alive is to become a Muslim; choosing to stay a Christian might mean a bullet to the head. But, initially unbeknownst to the women and girls thus converted, staying alive may not be not in the cards for very long. Many of them are indoctrinated in jihad, and trained to become suicide bombers.
It’s difficult to imagine the psychological mechanisms that would make such an intended transformation successful. Is it Stockholm Syndrome? It’s one thing to begin identifying with your captors, and another (I would think) to go and indiscriminately kill members of the very social and cultural group in which you grew up.
