Oh, and Vader, Palpatine, and Maul plot to murder each other more or less constantly through the existence of the Empire, often coming quite close to success, with everyone else who can plausibly claim to be Sith also trying to get in on the action.
For another example, in both Sith stories in SWTOR, the PC is betrayed by the Sith Empire, including by direct superiors and by the Empire as whole both times, and has to mount a personal crusade to acquire enough power and authority to just survive, and both times the collateral damage is immense. Betrayal is constant among the Sith, and makes many of them quite miserable. Vitiate/Valkorion/Tenebrae, gets so sick of betrayal (including by his lover, his son, and his daughter) that he hides out inside the PC's mind during the SWTOR expansions just for some peace.
