Moving this discussion to the proper thread.
Yes Cassian and Han are both willing to kill-but for completely different reasons. And Imwe (yes, he's the blind guy), isa gaurdian of the Whills. The force, as presented in the PT, is basically a magical power that chooses certain people to be able to wield it. Whereas in rogue one it's more of a religion, and knowledge of it isn't confined to the Jedi and the Sith. Yes, they're the ones that can 'use the force' or 'wield' it. But other other beings trust in the force, truly BELIEVE in the force, and yet cannot 'use' it. It's a lot more realistic to how real- world religion and belief works. Again, I apologize to mods if this is breaking rules.
