He doesn't know what he's doing.
He's turning himself from the victim's side to the Gox's side where no one will give any mercy.

It doesn't cost us too much to crowd fund and find the seller, then the buyers when the seller is caught.
When this gets picked up by the media to piss off every investors to find the seller, 100BTC? too easy.

Too bad he can't ask us to donate BTC to promise to discard data as there is no way to prove it's gone.
Not sure how putting his head out there for hunt for just 100 BTC is good for his life against... lots of people out there with lots of money.
