I read some articles/books talking about how the Jedi in Star Wars follow similar practices as buddhism. In Return of the Jedi, Luke did not want to fight Vader, but starts fighting once Vader says he will try to turn Leia to the dark side. After cutting off his hand, he decides not to kill him out of compassion
However, if Jedi are supposed to be compassionate and have to see the good in others, how come Luke doesn't try to stop Vader from killing the emperor and instead try to see the good in him also? Also, the sequels/prequels constantly show the Jedi killing other monsters and villains. Why don't they try to see the good in them as well? For example, Darth Maul.
