Agree with the OP. Butter is a likeable character and I've always felt sad whenever I killed her (can't really say the same about anybody else in "her" gang, but whatever). One may talk of "guilt by association", but frankly, I wonder how many people would side with the stronger just to have a chance at survival. I wouldn't mind a speech check (or even better, a sidequest) to have her change sides and leave the gang.
