True. It's his intentions in Skyrim which can be labelled as "Morally grey". Harkon's intentions may actually have changed since he became a Vampire, from being a horrific Tyrant to a man who just wants to save his species, by any means neccesary. There is a possibility that Harkon may also be insane, driven by guilt for the people he sacrificed. But thats just a theory.

Damn you, Vythur!
