No, I really don't think I miss your point. I should point out every film is not a deep drama with a message. The basic plot line for a Western has many people who don't deal with the villains for various reason, thus the need for our heroes. It would be a very short movie if the whole town took up arms against the bad guys.

To the second point, if someone is shooting at me, I take a little exception at my response being called "ruthless", I would say it is more in the justified range. Given everything, yeah, I would feel bad about it, but I would defend my family / friends.
