I wouldn't say that even. He was a guy that was obsessed domination and power, caring for nothing other than that goal. Not exactly the deepest antagonist but an adequete one nonetheless. It's not a plot hole that he spared you the first time and tried to kill you the second encounter, the Dragonborn was Miraak's equal at that point or at the very least had the potential to be because of the Bend Will shout.
