Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

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.
In Star Wars, can a Jedi kill?

In the last episode of game of thrones, Sansa asks that the North becomes independent and Bran allows it. Seeing this, Why didn't the other rulers ask for the same thing? Especially Dorne and the Iron Islands.
Why didn't the other kingdoms want to be independent?

In the episode Deutschland 93 from the second season of Narcos Tata meets Murphy in the plane from Germany to Colombia and says to him: I hope you enjoyed Germany. It seems that the most plausible explanation is that she recognised him as a DEA agent and noticed that he spent all his time in Germany in the airport, just like she did. However I didn't notice any sign of sarcasm in her voice, she seemed to be completely emotionless when saying this. This leads to a second possibility that she simply remembered him from the flight to Germany and it was just some small talk. However if this is the case then I have really hard time understanding the purpose of adding this scene in the first place. Is it one of these two options or something else? What is the actual meaning of this scene?
