Episode VIII
After defeating Darth Malak, Revan journeyed into unkown space, leaving behind the ones who accompanied him in his quests to find the Star Forge. Darth Revan's death is not known, and he is not spoken of after that.
Darth Turanus died by Anakin Skywalker when Chancellor Palpatine told, or rather ordered Anakin to kill Turanus.
Many people think Darth Revan was an ultimate Sith, far more superior than Bane or Vader. They are wrong. Bane is one of the few true Sith. Darth Revan quit the Sith and helped the Jedi defeat his own Sith Empire. Darth Vader attempted to kill his master, a Sith master, Darth Sidious, to save his son, Luke skywalker, a Jedi Padawn. No Sith would sacrifice a Sith Master for a Jedi Padawan. Darth Krayt, of course, was one of the greatest sith. He was able to manipulate and control Darth Talon, the Darth Wyyrlok's, Darth Stryfe, and very, very briefly Cade Skywalker. Krayt also controled more Sith and one of the largest Sith Empires ever. He was seemingly unstoppable at the time. Darth Wyyrlok was also a great Sith, Evan though he didn't have his own empire. His daughter and grand daughter were also Darth Wyyrlok at some time. Darth Talon was also a very powerful Sith. Quinlan Voss would've been a great sith if Mace Windu hadn't tricked him.
Darth Vader killed him.
The answer is yes
