Yeah. I would have said that Gen's main problem with losing his hand was coming to grips with how that had an impact on his identity as a thief, and possibly the loss of that identity -- although in the end he doesn't lose it totally (at that point; more so when he becomes king), as he goes on to steal the queen. Though I guess he loses a lot of his identity as a solitary thief, and that's a blow too.

Speaking of which, he uses the body shame fake in the second book too, right? Where everyone assumes he doesn't want to be seen with his hand, and instead he's off doing his own thing? Though not nearly as awesome as that cathartic moment where he holds up the hook in the third book.
