Again I don't have a problem with heroes killing in general, I just like the fact that some characters, like Superman, Batman, Spider-Man, ect. don't kill. It's just that sometimes it's nice to have a hero who is optimistic and positive and find ways to resolve the situations without killing.
You post that you do not have a problem with heroes killing in general, yet you immediately contradicted this position by handcuffing certain characters to an arbitrary "no kill" desire. Once again, you ignore
situations which demand the taking of life. It is not a routine, habit or desire, contrary to the pearl-clutching of some people regarding Superman.
Wanting Superman to have that "no kill" mandate all the time is an unrealistic desire, as it divorces him (a character who consciously places himself in the most dangerous situations for the purpose of stopping something/one) from any relatable emotional situation (observed or experienced) and behavior common to people throughout history.
As a member of a
population of a heroic fiction universe, where the very essence of the genre develops and includes threats beyond the capabilities of regular people to address, having a character act (or writers force him to act) as if the threats will always stop short of challenging his
unsought, but occasionally necessary solution (as in the case of
Man of Steel's Zod) renders the character as being the equivalent of someone represented on a coin: it may look like the person, but its a nothing more than a symbol--an idol in relief bearing no resemblance to the real person born with real heart & reactions, all to lock him into some Mickey Mouse-esque personality (which Superman did not have in his early published life either--a fact habitually ignored by those who want to deceive themselves into believing he was some Boy Scout from the start, as posted in another thread on this board).
It's just that sometimes it's nice to have a hero who is optimistic and positive and find ways to resolve the situations without killing.
Back to the
Star Wars example, how was textbook hero Luke Skywalker going to be "optimistic" and avoid killing while fighting his way through the Death Star, or while joining the Rebels' attack against it? What would you have him do, since the only logical option--the actual mission--was to destroy the station, knowing over a million lives were serving there. He did not
need to find alternate solutions as he was racing in the trench, other than to trust in / using the Force in order to make certain he would succeed. What would you have this textbook hero do as an option?
