If its his body thats being controlled, and whoever is controlling him(or the order given to him through the necromancy) can use his eyes to see things, why can he still move his mouth to speak and warn son of god?
Also, where in the bible or any scripture or any thing related to Christianity does it say "dont escape things"? I mean, I guess leaving everything to god could be considered giving up, but son of god doesnt seem to be a really... righteous christian, if he is one at all, so yeah. But even then, it still doesnt say dont give up or escape, it says the opposite!
