It is simple, his love for money more than his career had muddled his mind.  It is greed that makes him do things that he knows are illegal and yet thinks that he is smart enough to make people not notice his cheating.

If a person is consumed by greed, he won't think of anything but how to execute his plan on making more money.  The person will always disregard the people around them and only focus on taking advantage of the situation to make money whether legally or illegaly.

The topic has nothing to do with gambling but with a person's greed.


As far as I understand gambling and trading are not the same thing, even the risk involved is not the same thing.
