I understand your sympathy for children, and it is well placed.  But he's not a child anymore.  He's doing this to himself.  If he would rather eat 2 pizzas every night until he dies at 30 and never sees his kid graduate high school, that's all on him.  Being an adult means taking responsibility for you shit, I was raised in a very religious and sheltered household.  Think, people who drink, smoke, get tattoos, swear, and have premarital sex are all sinners and horrible people.  Most likely molesters and rapists and should never be socialized with or trusted.  Obviously, I became an adult and formulated my own opinions.  He's not a child anymore.  He's an adult, and he's doing this to himself.  Don't have sympathy for that.
