For me, this kind of article making bitcoin's image so bad, and some people might think that bitcoin is still a fraud and scam. Scamming your business partners worth of 63 million is huge money. Imagine that you are one of his business partners and he scams you taking your hard work money and vanish, I'm sure that you will be outraged. But I agree that killing is not the answer for every scam, because once he/she is still alive, you can assure that theirs a chance that they can bring back your money.
