It's not wrong... You can win sometimes too.
So, from what I understand, it is not wrong only because you can win sometimes. Let tell play 100 times and win 5 times. Play 1000 us dollar and win only 20. No problem because are lost the remaining 980. This is not at all wrong. This is fun. Can be more fun than lose 980 us dollar. Above all when you do this every day. Maybe every night too. Where find the money? Very easy. First your money, then the money of the family (mean the money of your wife, father, mother, and at the end the money of your children - money for their school, college etc), and at the end borrowed money. Only in this way you can achieve fully your aim have doing gambling. To destroy not only you but everything have to do with you. Can be more good than this?
