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.
That is the bad thing about your peers or your friends. I know that in that case they are just having fun, finding ways to spend some time together but the thing is that they introduced him into something that will ruin his life forever. I am not saying that friends are bad influence but most of the time, they are the great influencers of our lives so we must first decide if going with them all the time will be better for you.
