Gamblers tend to get greedy. It is, again, what hooks them to their games of choice. A gambler wins and thinks they can win again. In essence, the more you bet, the more you can win and the more you bet, also the more you can lose. Gamblers get sucked into the cycle. Also if we look at it from this perspective we all know that greed is a sin, so yes then gambling is a sin.Most true gamblers don’t stop playing when they’ve won some money. They think they can win more. They get greedy and bet more assuming they can keep winning. Even if a gambler leaves a casino with a profit, it is often not the highest profit they had that day. It is more often than not that a gambler will win and then ultimately spend at least some of their winnings chasing more money.
