I think there's a point in a person's life when everyone else decides that person can't be changed. Certain character traits simply and permanently become part of who they are. There must be some cut-off when parents give up in shaping their children and just accept the way they turned out, hopefully deciding they did a good job. Young adults permanently become bullies or jerks or unreliable or whatnot.
I believe there's always room to grow. I believe that no matter how old or set in their ways a person is, they can change if they want to. Maybe I need to believe that because of some of the people I know and love or because of who I am and traits in myself that I don't care for. Or maybe sometimes there are things/people that are too important to give up on. Whatever the case, I don't think there's ever a point when we can write a person off. You have to have faith in them and care enough to help them change, if they want to.
