One line inStar Wars: Episode III - Revenge of the Sithhas me fairly convinced thatMace Windumay have fallen to the dark side, and we all missed it. Mace Windu is one of the most fascinating Jedi inStar Warsmovies and TV shows, and he arguably hasn’t gotten the attention he deserved. Throughout the prequels, Mace Windu came across as an incredibly respected Jedi among the other Council members, although it was also clear that he was one of the harshest towards Anakin (even when he was a child).
That difficult relationship continued through toRevenge of the Sith, which ultimately ended with one of the most important moments inAnakin Skywalker’sStar Warstimeline: his confrontation with Mace Windu in Palpatine’s office. It was in this scene that Anakin ultimately chose Palpatine over the Jedi, sealing the fate of the galaxy and the Republic. Before he was sent flying out the window,Mace Windu delivered one shocking, easy-to-miss line inRevenge of the Siththat has me really questioning whether he had fallen to the dark side.

Mace Windu’s Logic Echoes Palpatine’s Own With Dooku
While it may seem impossible that a Jedi as well-respected and powerful as Mace Windu could have fallen to the dark side,one jarring line inRevenge of the Sithsuggests that, at the very least, Mace had blurred the lines between the light and the dark. When Mace Windu was attempting to convince Anakin that killing Palpatine was the only solution, he told Anakin,“He’s too dangerous to be kept alive.”
This logic from Mace Windu echoed the exact same language Palpatine had used earlier inRevenge of the Sithabout Count Dooku. Anakin was distressed about having killed Dooku when Dooku was weaponless, as that wasn’t the way of the Jedi. To reassure him he had done the right thing, Palpatine told Anakin,“He was too dangerous to be left alive.“The issue is,Anakin had been right; killing an unarmed opponent was against the way of the Jedi.

This logic from Mace Windu echoed the exact same language Palpatine had used earlier inRevenge of the Sithabout Count Dooku.
Now, knowing Palpatine was one ofStar Wars’most powerful Sithmakes it rather difficult to blame Mace at this moment. However,this was not the first time Mace Windu had argued that someone needed to be killed because of the threat they posed. In the canon bookStar Wars: Dark Disciple, written by Christie Golden, it is Mace Windu’s idea for the Jedi Council to have Count Dooku assassinated at the height of the Clone Wars—and they even hired former Sith assassin Asajj Ventress to do it.

This raises questions about what constitutes the dark side and ‘falling’ to the dark side, although, when approached without bias in favor of Mace Windu, it’s not a good look that, on multiple occasions, he was arguing in favor of killing the Jedi’s adversaries.This is also indicative of a larger issue that had emerged within the Jedi at the time. The Jedi of course did not deserve Order 66, nor were they ‘the bad guys.’ Yet, it’s clear that at some point they had abandoned their core values.

Clone Protocol Order 66 caused once-loyal Clone troopers in Star Wars to wipe out the Jedi, but a handful managed to survive this initial purge.
After all, the Jedi had gone from peacekeepers to soldiers who were fighting along political lines. This is precisely why so many Jedi ultimately became disillusioned with the Jedi Order and turned to the dark side, from Barriss Offee to Anakin Skywalker. It’s particularly alarming in Mace’s case, as he was the Master of the Order. If he had fallen, then so too had the Jedi Order. WhileMace Winducertainly wasn’t a full-fledged Sith Lord, thisStar Wars: Episode III - Revenge of the Sithmoment suggests he briefly did tap into the dark side.
