Its just dumb and mind boggling on why someone would be using up their hard earned funds into something which could really vanish out on an instant? If they had just mind off on how hard to earn
money then they wont really be touching gambling in the first place or simply made out some bets but on a very minimal amount that they could use but since human beings are naturally greedy
then there are indeed times which we cant really able to resist such thing.
You are describing what is compulsive behavior. Problem gamblers don't just lose money and think it's okay what they are doing, they know it's wrong, they know they have to stop gambling, they know they shouldn't take a loan to keep gambling, etc. but the addiction gets the better of them and leads them to keep gambling while they are in a kind of trance even though they know the consequences.
