But he wasn't uncaring, much- he did a lot of tough-talking, about just abandoning his friends et al (they'd served their purpose, cut them loose- whatever) but when it comes down to it he can't, and he doesn't- that's part of the revelation at the end (for Pinch) at least that's my reading. He talks tough but doesn't follow through- unlike the actual bad people, hence him rescuing Therin from the noose (even before the book starts) and sticking with a drunken Maeve and the greedy halfling Sprite.
Again, just my reading.
Oh yeah, it was >20 years ago now, and my memories of this one aren't very clear to say the least, that was just the memory i have of it. Quite possible I'd like it more now!
