There were counter arguments that his child also would turn out a gambler like he is.
This argument is vague not because the father is a gambler the child will also grow as a gambler too? not unless he'll let his kid grow with him together in the casino.
Yeah, in fact, how will a man in his right sense even allow his kids to make the same mistake he is making unless he is totally cursed by his forefathers ? An addicted gambler even as a father should always know better what he is trying to battle with, so trying to bring your kid into the picture is just evil.
Secondly, if it were to be genetic, I am sure I should have been a hardcore gambler by now, but it is a path that everyone can decide to take in their life and a matter of choice. A child who can see the impact of gambling in his fathers life even if he gets to know he does will never choose that path.
