In the Disney Cannon was Maul a Sith?
Looking at some of the discussion around this question. there seems to be some confusion as to the status of Maul's Sithhood in his later years.
Wookieepedia lists him as 'Sith (formerly)' but the reference seems to be The Phantom Menace which would not deal with his fall from the Sith.
The rule of two, seems very flexible and easily broken. Apprentices look to replace their masters. Masters seem to be willing to trade up when needed. So while Sidious does not consider Maul a Sith, it does not mean that he is correct.
Maul looked to take on his own apprentices and overtake Sidious. He was still a dark side user, he still used Sith technology. So he was acting in a Sith-like like way.
Is it that there is a difference between a Sith, and a Sith lord? He dropped the title 'Darth' which we associate with Sith Lords.
Was Maul still a sith in any way in the later years of his life?
