Not sure how you can comment in the direction of believing about mistakes. If you had money in my bank and I showed you £10,000 but then actually used this money for my bad trades and still showed you £10,000. Would you believe that it was an honest mistake if then when you tried to take your money back, they were not there but burnt in trades? Is it a mistake to use other people money for your means? If so, yes then he made a mistake. Did not steal. I would have thought that for money WYSIWYG principles apply. E.g. what you see is what you get and have. And not that what you see is …maybe...what you have but not get.
