I don't think you can ever change a takers ways. If there is a way they will take, if there is a means they will take. They will never change, they are the takers they are the ones that think the world owe them, that the world revolves around them. They will never change, they may leave, but more likely come back when they can not find a place to take from as easy as they had it here, maybe new names, Dragnet, old American TV show), "the names have been changed to protect the innocent guilty".
It's a fair option to start afresh, but different actions are required or things are likely to repeat. I'm ever hopeful that people can adjust to the changing times.
