I can't say you're a bad father, but I'm confident that a good father wouldn't knowingly allow his child to gamble. This means that a good father knows what's good and bad for his child. Personally, even if I had full access to ensure my children became responsible gamblers, I'd prefer not to allow them to gamble.

The reason is that we can't keep an eye on them forever. There's a phase when children grow up, which can create a distance between them and their parents, and they often no longer want to be treated like children. I worry that they could eventually become aggressive gamblers. That's a very real possibility, so I prefer not to give my children any access to gambling, or even just to watch it.
