Quoting from your link, keeping its bolding. Chilling. Poor Stephanie.
Psychopaths are Losers who view themselves as Leaders. As weve seen, unless theres a specific advantage for him, a psychopath never admits to being wrong, to doing wrong, to having wronged anyone. Whatever he does wrong to otherscheating, lying, manipulation, hurting them emotionally and physicallyhe manages to project blame on the victims and on those around them. In fact, the psychopath will see his cowardly actions as superior; on a higher plane of existence than the rest of humanity. Rather than seeing himself as the pathological person that he isessentially, a Loser who spends his life parasitically using and taking advantage of othersthe psychopath is likely to see and describe himself as a maverick: a lone dissenter, a willfully independent hero ahead of the pack, who rejects the dated and commonplace notions of right and wrong and of truth and falsehood. Ethical human beings, who care about others, are considered by the psychopath and his followers moralistic and narrow-minded.
It's a jungle out there. There are many reasons to be homeless. Many do have family, but you can't force someone to live with you. They are often mentally ill and it's very hard to get treatment for an adult. If a family member or a friend is an addict, especially to meth, you don't even want them to know where you live! You can't fix an addict. It's heartbreaking for family, but they just have to let go in order to let the addict find their way to recovery without destroying everyone around them. My Dad was an active alcoholic until his mid-60's. Addiction is awful for everyone concerned.
