The sith seek the rule of 2 and forever holding power for themselves, the Jedi supposedely try to take a role where they do not rule, but provide protection and guidance for the galactic Republic. Both clearly a slippery slope. But yeah you get situations like Darth Bane jumping onto a rancor forcing his will onto it, enslaving it to do his bidding and riding it through a dense forest before just tossing it aside like a worthless tool when it is no longer of use to him. The idea that they wouldn’t do the same to a person who can’t protect themselves is pretty likely. We see them convince people to shoot others… I’m sure morals/ethics are out the window at that point
