Lance is that type of person who realizes the terrible things they have done. Kinda like Michael mixed with Niko on GTA. He's killed people, sold people, and smuggled people around the country for a pretty penny, and then he drinks all of his depression away and then he feels bad about it. That kinda person who has remorse for what they did, shows that their not terrible all the way, It is okay to feel regret and guilt for whatever it is that you done. no matter what it is. because you live and learn from those mistakes to become a better person, especially if you were a kid. Don't let anyone tell you that you are still that person from your past, because they don't know you, because at the end of the day they don't think or care about you. Hell they are probably more miserable then you are. don't let anyone tell you different.
I love you Lance, i know you can become a better person again
P.s: This is not a spoiler. None of this contains future events obviously. Just how i feel how lance will turn out in the end, but i'm most likely wrong. :)
