In fact, short-selling should be encouraged. If there had been more of it in the past, stock markets would not have gone up so much. Rather than life companies blaming the hedge funds for pushing the market down, the hedge funds could blame the insurers for pushing it up. They won't, because it would be biting the hands that fed them. It is because there was buying at ridiculous prices that the hedge funds have had the opportunity to pick up a few crumbs of profit in the bear market.
