2. I never felt guilt or wanted to return the money. Casino is a very shady business and the owners of these platforms dont care about their players or their losses and will do anything to milk their customers out of their last dollar. So i feel no sympathy. I outplayed them at their own game.

Taking advantage of their system is one thing, but not feeling guilty at all is a very bad sign..

You did not outplay them at their own game, you abused a bug instead of reporting. That I personally consider cheating/stealing. And it doesn't matter whom you're stealing from or whose system you're abusing, it's just not right and nothing justifies such bahaviour.
