Sure he got hacked but he is responsible to keep his account/computer as secure as possible but of course the case is different when it happened because of eBay themselves. He also got the money back from Paypal and you have nothing so in the least it would be only fair to split the money and even the losses (until the hacker is found). There are also certain rules and laws because each finished auction on ebay is an actual contract so I do recommend you to look into it and don't give up.
