Q: In Star Wars movies, Jedi often kill their opponent (for example, Obi-Wan kills Darth Maul in the first movie and again Obi-Wan, at the end of the third movie, leaves Anakin dismembered and on fire, thinking he is going to die), but when the Chancellor orders Anakin to kill Dooku, he says:    I shouldn't. This is not the Jedi way.   So I wonder, can Jedi kill?   Or is it a mere plot device to make the fall and the internal struggle of Anakin more romantic.

A: In Star Wars, can a Jedi kill?

Q: In episode 4 of season 1 we see Locke taking its first look at "the monster" (~30:00), while hunting boars on his own. He seems to be looking straight at something, not just randomly towards the direction of the noises. But then (~38:53), when asked by Walt's father, he says he didn't see it.  Why does he lie?

A: Why didn't Locke say he saw the monster?

Q: In one of the more famous Pulp Fiction scenes, Jules and Vincent are eating at a diner when Ringo and Honey Bunny decide to rob it. Their attempt doesn't go well.  At one point, Jules tells Ringo to open up his wallet and take out $1,500.  http://www.youtube.com/watch?v=3PeyiU3uWJ8&t=1m22s  Now, I ain't giving it to him, Vincent. I'm buying something for my money. Wanna know what I'm buying, Ringo?     "What?"    "Your life. I'm giving you that money so I don't have to kill yo' ass."   What does giving Ringo $1,500 have to do with not killing him?

A:
Why did Jules have to give Ringo $1,500?
