(Spoilers in the question)
In Disney canon, has a Jedi ever used only light side techniques/powers to kill a Sith?
Some battles I can think of that don't count:
- Obi-Wan defeats Darth Maul in The Phantom Menace, but Maul is shown to survive in Clone Wars and Rebels.
- Anakin kills Dooku in Revenge of the Sith, but he uses the dark side at Palpatine's goading.
- Obi-Wan kills General Grievous in Revenge of the Sith, but I don't think he's considered a Sith. (Correct me if I'm wrong about him being Sith, but back it up with canon citations, please.)
- Anakin kills Palpatine in Return of the Jedi, but it's questionable whether he counts as a Jedi here. If we have canon evidence that he didn't use any dark side techniques/powers, this would count.
Most other questionable/debatable instances are okay. Possible mitigating factors I can imagine:
- It might not be clear whether the person is a Jedi at the time of the kill. (Anakin was redeemed, at best, only seconds before killing Palpatine.)
- It might not be clear whether the Jedi used dark side powers. (Anakin killing Palpatine.)
- It might not be clear that the Sith is dead. This one doesn't have to be completely definitive, but try not to be too liberal here. I'm sure a lot of people thought Maul was dead until he showed up in Clone Wars, so prior to that, Obi-Wan defeating him on Naboo would have been a good example. But just falling off a ledge and someone looking over and not seeing them probably isn't enough by itself.
If any instances are not crystal clear, please just make sure you explicitly state the mitigating factors. I'm not looking to debate or give a strict set of rules about what counts and what doesn't. Just use some good judgment. Readers can decide for themselves.
I'm not interested in Legends here. I'm certain we can find examples in Legends books or games. This is about Disney canon only.
(It might be worth noting that while I've seen a little of Clone Wars and Rebels, I haven't seen much. So there might be obvious examples in those that I'm missing.)
