Just curious if it was possible to keep the NCRCF trader (Carter) alive/interactive after you finishing "I Fought The Law" having sided with the NCR?
The Powder Gangers at the prison will all be tagged as hostile once the assault begns, obviously but is the any way to "undo" the tag afterwards (as Carter doesn't need to be in the fight)?
I've tried sneak killing everyone in the prison (except Eddie) beforehand and I've never risen above "Hated"/"Sneering Punk" reputation after this quest, "Ghost Town Gunfight" (sided with Goodsprings while remaining hidden) and "Booted" (haven't completed "Why Can't We Be Friends?", yet).
Thought it'd be cool to keep him running a one-man operation out of his old cell block (I also felt a little 'sorry' for him... though not enough to not steal his Schematic, of course).
Cheers.

NO!
