The darkest irony of Shadow Lord is it shows us how Maul was Sidious' perfect apprentice
From what we see in the show, Maul is the one who learned the most from Sidious and internalized those teachings, we repeated see him do the same things Sidious does, uses the same tactics, hold to the same mindset, and just generally wholeheartedly embrace everything Sidious taught him, Maul is his apprentice in a way Tyranus and Vader never were, they're too proud, too arrogant, too angry, spiteful, impatient, entitled, Darth Maul is all those things too, so is Sidious, but like Sidious and unlike the other apprentices Maul is able to better control and use those qualities, Maul is a Sith Lord in a way Dooku and Anakin never were
