I don't feel bad for gamblers who lost a lot of money. It was their choice and if they won they'd be bragging about it everywhere and buying stupid useless shit. We shouldn't help these people financially they have to learn from it and suffer the consequences.
If they are to consider lowering their bets in the game, then it will surely not satisfy their hunger to play more. Basically why people play and gets addicted is when they bet a huge amount and they win. If they are to bet small amount then its sadly but true, its boring. So, to help someone who lost, then an advice would do for him to limit playing, or else, work hard to have too much to spend in gambling without worrying of losing everything.
