It always amused me that during the temple massacre - at least, when we see him enter the council chamber to kill the younglings - Anakin doesn’t have the Sith eyes. It’s only when he’s on his way to kill Wat Tambor that he’s sufficiently evil to qualify. And then he has a good cry over all the dead Separatists :’(
This is why, if I could shoot new footage for it, I would love to have Anakin go to Mustafar to hunt down and kill a group of surviving Jedi.
