Well I think Kaneki's main goal still is to be loved, like little shironeki said soon before his transformation. So I think (and sincerely hope) he will at least try to save Hinami. But as Touka said in TG, this desire to be loved is a purely selfish desire, ("a good thing, a bad thing, it doesn't matter") he is prepared to do anything and doesn't care whether it is morally the right choice or not.
Also, one important question is, from whom does he want love? Is he so desperate that he will take anything he can get? If that is the case Eto really has put a wedge in his psyche by saying she loves him. I think his future actions really depend on whose love he values/thinks he will get as that is where his loyalty will lie.
At least I think we will get an explanation for his behaviour sooner or later, a major theme in TG is it's moral ambiguity. Just making the main character "evil" without any kind of insight into his thoughts would go against all that.
But well, that is just my take, he is also suicidal and pretty far from sane, so maybe he is not that predictable.
Oh man, another double issue wait is gonna kill me.
