Hamilton had already lost the right to the championship by bodging several starts during the season. Nico was simply ahead in the points and didn't need to attack him to be WDC; that was the logic. For Mercedes, their job was to finish 1-2, giving the win to Hamilton and securing Rosbreg WDC. Hamilton tried to spoil Rosberg's chance by backing off, so that the German lost places, and championship as a consequence. I hope I was wrong, but I suspected Hamilton to slow down to provoke Rosberg in an overtaking move, only to ram him or drive him off the track, or damage his car. I expected a desperate "Schumacher move" from Hamilton, and I understand why Rosberg did everything to avoid that confrontation. I think Hamilton is capable of anything now; I mean that. That's dirty and unsporting behaviour, mostly against a team mate who helped him in the past (remember Monaco?) . Rosberg is a worthy champion, who left Aby Dhabi with his character unblemished. Now Hamilton is just the villain of the story.
