I've gotten pretty used to unsympathetic characters getting redeemed to some degree or another. It's really really common in anime. And sometimes dubious characters dig themselves a hole. I'm less aware of initially sympathetic characters turning bad, especially if they're not an obvious Charismatic Villain candidate. Liveship Traders trilogy is having a good example of this, as well as some more standard redemption arcs.
Also, hey, democracy in SF! Okay, more like a democracy of oligarchic family heads, but it's something.
