This is very upsetting to know. The yetser h has myriad of agents in the world. All one can do is say a capital Tehillim with the intention of helping the victims. And at the end of the day, one day more is one day closer to his annihilation and we’ll be walking on his ashes.
This story reminds me of something the Ruhziner Rebbe and Rebbe Elimelech said. That the children abducted into the Russian army from the mid-1800s — the Cantonists — were the souls of the fanatics that burned the food supplies of Yerushalayim when fighting the romans. Knowing they would be forced to convert and eat treif and break the Torah was anguish to their souls.
Could this be a similar case?
