I think gambling always ends up bad in the end. Nobody is immune to addiction.
No I don't think so if you will only gamble what you can afford to loss than even if you regularly gamble that won't affect your social or financial life.
Gambling is only bad for those who can't stop themselves even after losing so much and can put anything he/she own in gambling to recover his/her past losses.
Gambling is good way to get entertained.
Gambling will affect your social even if you only gamble what you can afford to loss. Gambling too much can be bad, even if the money is easy money, gambling too much can make gambling a habit and not good because you can be addicted. Gambling isn't a good way to get entertained.
