Hedge funds frequently have charitable foundations and pension funds as limited partners. Unless the hedge fund is just a family office, there's a high probability that the "little guy" will be impacted, somewhere.
I can't tell you if your schadenfreude over hedge funds losing money is right or wrong, because that's based on normative values. But I'd encourage you to adjust your understanding of the financial dynamics involved.

A hedge fund is an investment fund that pools money from investors and then invests it according to the hedge fund's strategy. So, the primary people who will benefit or lose are the people who invested their money with the hedge fund. Hedge funds also tend to take a percentage of profits as part of their compensation.
I don't see what connection there is to the notion that the system is rigged. No one is obligated to invest in hedge funds and the people who do are aware of the hedge fund's compensation structure. Anyone who invests money is aware that investments have risk and can fail. The purpose of a hedge fund is to invest money to generate (better-than-market) returns, and so the hedge fund will be compensated if that happens. The fact that they're compensated from profits acts as an incentive for them to actually generate profits.
