Well that was pretty cursed, purely for the number of 10s showing up on the side of mortal terror.
… How does this help? The issues he just talked about were all about people crawling into his head to make him a monster. FSB could protect you from black magic backlash but not what they directly do to you.
A major point of my argument was that they needed to mindfully look out for each other to avoid getting caught and helping deal with it when it does happen. Unless we're leveling up before going to confront Peabody then this is essentially planning to be under the power of monsters. Some sort of active defense to stop that from happening would be better on every metric.
I'd also like to point something else out about this situation in particular; not once does Peabody make someone else perform magic, even when it would have been obviously better for him. When he forced Lucio to kill he made her do it with a knife even though turning her into a warlock would have made everything worse for the council. When he tried to flee he had some young wardens grapple people instead of casting or even ordering the golems with them attack.
I don't think he should be able to make people use magic; his hypnosis doesn't appear to go so deep as to make people exert spell casting levels of willpower on his behalf.
At the end he talked about his friends being used by the other side and made into warlocks that will either die in the fighting or have to be killed. Turns out he was not just worried about himself, but about his peers too. As for if they can be made to use magic Molly cannot even roll those dice, she does not have a place to start only a brief vision of mind control happening to Carlos from the outside.
