I’ve never been a huge fan of the hallway scene. It’s always come off to me like that’s not something Vader would do, never in the OT does he go around chopping up Rebels with his lightsaber. He doesn’t slice and dice Echo Base, and 15 minutes after Rogue One he doesn’t hallway scene the Tantive IV a second time. The Sith most likely to do that feels like Maul. Vader is a military guy, Palpatine is a politician, Dooku is somewhere in between those two. Maul is the deranged serial killer who’d chop up a room of rebels.
