My 2 cents on the whole compassion thing when it comes to celebs:
If you don't want to be poked fun at, humiliated, and what-not, don't do stupid ****! It's as simple as that! Don't go all soft on Justin now that he is actually doing something that is not only stupid, but poses danger to his health. If people go soft, he won't get better and change his ways. It's called tough love. Gotta let him know that this **** a'int cool.
