Has American Sniper become some "Litmus Test"?

28. Chris Kyle is no hero!

A hero, to me, is someone who is willing to sacrifice his/her life to save others. Example: the teacher who put herself between the gunman and her students at Sandy Hook School. Or a parent, letting a child escape, while they stay behind to fight off a bear, etc. Knowing that they could likely die.
Kyle was one of, if not the best sniper this country has had. He was trained to do this job. And he did it exceptionally well. But he's no hero. Just a highly skilled sniper, who loved being paraded around as a hero. He fed into it, and a book has exposed him to be a convenient liar, whenever he felt the need to be admired again. I don't know why people need to inflate certain people. The good and the bad weigh evenly on his scale, and this film, will now expose the real Chris Kyle. That's something filmmaker Clint Eastwood, and Kyle's widow and family, cannot escape from.
