Some of us are overlooking some important points. First, his life wasn’t “shit” before this media storm broke. He was doing what he wanted where he wanted and doing it well. It wasn’t until what the state intended to remain private became public that it all changed.
Secondly, there is no reason whatsoever, beginning with Luke’s own words, to believe that he was not guilty of harming his young relative. He should feel remorse, and it is to his credit that he does so. He is the one who feels he needs to make up for his behavior and earn respect. Those are his feelings. There is, again, no reason to believe he is not sincere.
