That is why later on Palpatine spoke highly of Maul who was a sith all his life but shit on Dooku expressing how little he thought of him. As a fallen jedi Dooku was still someone who knew empathy and we see that in AOTC with him trying to turn Obi-Wan due to the master apprentice connection.

Palpatine also was so much a sith he was stupid enough to actually harm Anakins son forgetting the only reason he even got Vader was the promise to save his wife and child. In the eyes of Palpatine there was no way Vader would ever raise a hand to him but forgot Vader would do ANYTHING for his family.

In TESB not only can you see Vader hold back against Luke but he does his best to not harm him until Luke lands a hit on him. In a brief moment the rage/anger gets the best of him but he still collects himself wanting his son to join him.
