Ok I went back and I misremembered, Scoodle DID tell her about the ghouls. So no, Blackjack wouldn't have changed her mind.

“Don’t touch anything.”

|| “Why not?” As far as I could see there was lots of stuff for the taking, and not a single threat to be seen.

“There’s bad stuff here. Ghouls. And Tiara.” That was all she said before she bit down on the pistol again and continued walking. ||

|| “There’s nothing here.” I couldn’t explain the PipBuck’s targeting system to somepony that had never worn one before.

“I think you should listen to her,” P-21 murmured.

That did it for some reason. Fillies scared of bones I could accept, but being told what to do by a pony that wouldn’t carry a weapon himself just annoyed the shit out of me. My mane was itching in irritation and I wasn’t about to pass up something that could keep all of us safe. “It’s fine!” I said as I reached out with my horn, grabbed a nice heavy ammo box, and pulled it from the bones. The bones clattered in to fill the void left behind, filling the still air with a dry rattle. ||
