Its possible that a ghoul going feral is akin to dementia, which means in theory its treatable. Im not against the concept at the very least.

Oh boy ya aint heard of the Midwest Brotherhood? Let me give ya an idea of what they were like, Caesar's Legion but not technophobic would be a solid summary. They broke from the standard doctrine pretty notably, for example ghouls, super mutants, and even intelligent deathclaws were recruited by them. I like the idea of the Brotherhood fracturing ideologically.

And yeah I kinda get it but ill wait till we get more lore on what happened to the NCR before I cast judgment.
