I also think that it's important for everybody to remember, too, that people such as Amy Winehouse, Lindsay Lohan, and Britney Spears suffer from honest-to-goodness illnesses. Alcoholism, drug dependency, and mental issues are all very clinical issues. No doubt that, if you look into the history of their families, you'd likely discover that other members of their family, both alive and dead, had (have?) similar issues. The media leaps on these men and women with these kind of issues because they sell. Nobody ever considers, though, that with a bit of help, treatment, and care (even if they themselves don't think they need it), they are no different from you or I, and that absolutely everybody has the chance and suffers from the vulnerability of a sort to end up just like they've ended up.
Some of the most respectable, kind-hearted people I have ever known are former drug-addicts. I know many people I respect greatly because, in discovering that they were drug-addicts, cleaned themselves up and tightened the screws in their lives more than sober people had. One of my best friends used to be addicted to absolutely every substance under the sun for several years, until he recognized his problem, got help, and set himself on the right path. Enough love, care, compassion, attention, and encouragement, and he came out better than most people I know who've never touched a drug. When I have children, I would trust them soonest to him than anybody else besides my mother and father.
I'm not condoning, at all, the use of drugs, though! I'm just making sure that the point is put out there that these "worst" people might one day have the chance to redeem themselves and do a lot of good for the world, and that when they do, we should embrace their cleanliness, sobriety, and history, and accept them wholly for who they are.
