Did all those sacrifices meant anything to Jack?

His family, Arthur, Sadie and lots of other folks sacrificed so much to keep him away from being like his fathers (an outlaw), and some of them died for him to have a good life. But in the end of rdr1 he chose to be an outlaw. I think he didn't learned anything from deaths of everyone around him. He should've understood that when you became an outlaw once, you can never leave that life behind.

What's your toughts?
