There's nothing horrible at all about shorting, it's just about investing in the other direction. It's horrible if funds try to push a company down on that basis, but otherwise it's normal. It's 'good' because you want people betting on the other side of irrational hubris - if the market is way-overvaluing a stock, you want them to 'lose' and for the stock to come to something within reasons. Shorting helps prick mini bubbles, or stabilize them, before they start to get way out of hand.
