I felt guilt for convincing the people to come into gambling when some of my friends I invited them for gambling got addicted very soon so we need to pick the right kind of peoples for making them gambling if we have the poor people to make into gambling then it may affect them and their family life.
This is the almost the similar scenario which has happened to one of my friends as they wanted to just hang around and enjoy so invited few friends to casino. But now out that one has got addicted and plays for money and not for fun. So he feels bad about it.
There are many similar story like that out there, inviting friends to the casino for the first time but he become addicted into gambling. One of my friend is also like that.
