It is not our responsibility to help the poor but we can do it voluntarily out of love. If it is necessary to help a poor family, then I will sacrifice my one-month gambling habit to help them. I could stand and continue with life even without gambling but it will be hard for me to see a family who is suffering because of poverty. That will not solve their problem but it could ease their suffering.
The money I use to gamble are for making fun, just a bit out of my money, so I can sacrifice it to poor people. Giving to poor people is not our responsibility, that is not a lie, but it would give me easy and okeasure to help the poor in need than to gamble, but i have my choice to make. Everybody have their own choice to make about it. Only people I think are not likely to help are those gambling addicts that can even use the money they suppose to use to eat or do something important to gamble.
