Could you clarify this a bit please theymos.  How did he have access to the user deposits?  If he was "borrowing" them without authorisation, that's straight up embezzlement regardless of whether he intended to return them at a later time.  When did the shareholders become aware that he was spending user deposits and how did you become aware of his intention to replace them with money from BitcoinGlobal?  I'm confused about whether the shareholders effectively authorised him taking a "loan" from the business post hoc by agreeing that he would pay back the misappropriated funds from BG money.

I hate to say it, but if you send Nefario user funds knowing full well that he has already misappropriated funds, you're laying yourself wide open to liability. His access to funds needs to be blocked and a way of returning user deposits worked out which doesn't involve Nefario.
