[Blackbeard D. Kuma]

I have a sneaking suspicion that Doflamingo is going to end up being a sympathetic villain. With Vergo's comment to Law that he knows nothing about his master's past and how caring he is to his subordinates, Doflamingo isn't seeming as bad as I originally thought. When everything culminates in Doflamingo's defeat, Fujitora is most likely going to capture and arrest him for his crimes. It's approximately at that point where we'll see Fujitora's real nasty side (we caught a glimpse of it back at the bar). Most likely he'll let the strawhats off the hook for their contribution to stopping Doflamingo, but that's where he'll cement himself as a future obstacle.

Just giving my two cents on how I think this arc will end.
