Chris Kyle was a human being, a Texan, Navy SEAL, father, husband, brother, friends to many, and a hero to many; this, at a time when we need all the heroes we can get. I knew him to be a good person, regardless of all the hype floating around in the media.
To this day, just always treat people the way you want to be treated. Whether it's family or friends or co-workers, I think it's the most important thing. Whether you have success or don't have it, whether you're a good person is all that matters.
