We have an epidemic of people who don't understand morality, and that's starting to show in our popular media in ways that old media understood to be wrong.
When Luke Skywalker blew up the Death Star and killed hundreds of thousands of people, he didn't do it because "those people are fascists and I don't like them". He did it because the Death Star posed an imminent threat not only to the Rebellion but to the Galaxy at large, so destroying it was not just the moral decision, but the only rational one if he was to save the lives of billions of people.
Also notice that Luke didn't just rush into Jabba's palace and start cutting people up with a lightsaber, and gave Jabba the chance to turn over Han Solo peacefully. He even gave him one last chance while standing on the plank above the Sarlacc pit, and this was after Jabba tried to feed him to the Rancor. He had R2-D2 conceal his lightsaber inside him because he knew Jabba might pull what he did, but gave him the benefit of the doubt and multiple chances before deciding violence was the only option.
The stated reason Jedi use lightsabers instead of blasters is they're "more civilized", but from a storytelling perspective, a lightsaber is limited as an offensive weapon by its short range. A Jedi can use a lightsaber to block blasters, or even deflect them back at someone who's shooting at him. But it would be very difficult to mass murder people who have the ability to run away. In the original trilogy (before the prequels ruined everything), Yoda is never shown using a lightsaber, and he even tells Luke "wars not make one great" to emphasize the point that the Jedi are supposed to be peacekeepers, not killers, and violence should be a last resort.
But when you look at more recent Star Wars media like The Last Jedi, morality is all over the place. When Finn and Rose go to Canto Bight, they free a bunch of animals called fathiers which proceed to stampede through the city, causing untold amounts of property damage and probably injuring or possibly even killing hundreds of people for no real reason other than to spite the rich. But they don't do anything to help the slaves who would be forced to clean up their mess.
