I just don't know what to think in this case. Was the owner drunk or having some health issues? Maybe the wallet and funds were inherited by someone who has little knowledge about Bitcoin and was trying to make his first transaction. It could also be a human error from someone knowledgeable. I think is ethical for the F2Pool to refund the funds after deducting some expenses, doing that will make their reputation rise in the industry. As the story unfolds I just hope it has a good ending and that the funds are returned to the owner.
