Uhm, because they are the bad guys? John Wayne films are pretty clear on why the bad guys are considered bad. I realize that these films are not high brow entertainment, but factual honesty is always a bonus. Witty false statements playing on a cliche kind of irritate me.
Yes, that's understood. But what are the gunslinger character's motivations behind wanting to kill the bad guys? After all, we encounter really bad guys all the time in our lives, e.g. Jared Lee Loughner. If he were out in the wild, would you be willing to seek out and kill him. It takes a certain kind of person to be motivated to do this. What are those motivations? For being a Western that delves into some of these…
Have you actually watched any of the John Wayne flicks? The motivation is pretty self explanatory. Its like asking why the military in ID4 wants to kill the aliens. Getting shot at first is generally considered a basic reason.
