Why didnt hacker just take far less and get away with it? For example just ETH worth million $ or so. They would not shut down the DAO, nothing would happen. Now he lost everything.
This makes me think it could be something planed. To bring down dao, hurt ETH or maybe even inside job or whatever.
That could be true. He could just take less than 1 million and sell short in the market to make profit and then then return the stolen 1 milllion to the DAO.
