At first I was even looking at this story to be linked to a man but surprisingly, I don't know that females can still get this far be of being a gambling addict to steal such an amount of money, This is addiction and greed coupled together, I guess her aim of stealing this money would have been that she wanted to double down the money since it wasn't that a little amount, hoping that she will make an huge amount of profit.
That is an example of when someone is addicted to gambling and cannot manage it well. I am sure he chose to steal customer money because he thought if he won with a profit of 10 or 20% or even 2x then he would get tens of thousands of dollars in a short time. I am sure he did not gamble for fun but made gambling as one of his sources of income. Someone said never use your salary to gamble especially by going into debt. Now he chose to steal to gamble. This is really very bad because he has chosen to destroy his own life.
