It sounds like Ner'zhul to me...

He's always been pretty self-serving. o.o

The way I read into all his backstory anyway.

Look at it this way: Beforehand it could have been interpreted that he didn't want the Orcs to become the Legion's servants, because he would lose his control.

It also could have been interpreted that he wanted off of Draenor to save his own ass.

His life as the Lich King just speaks for itself.

Him as the good guy hero Orc just doesn't work for me.
