Interesting song lyrics.
My view (for what its worth): Heaven and hell are just metaphors for what people think of you (typically, once there's no longer anything you can do to change people's views ie. when you're dead).
For example, the vast majority of sane people absolutely detest what Adolf Hitler did. Therefore, you could say he's 'in hell'.
Gandhi, by comparison, was probably the coolest public figure I can think of. Hardly perfect, but brilliant all the same. Lots love Gandhi, so we can say he's in heaven.
Now, to try to get their children to behave like good little boys and girls, parents might tell their children if they're good, they'll go to heaven and if they're not, they'll end up in hell.
Ideally, the child then grows up to be a kind human being who behaves ethically whenever able to.
Ultimately, with them both likely merely being metaphorical nonsense, you're free to live your life as you choose (though beware enforcers of the law). Because, ultimately, when you're dead, you're dead. You're no more and you need never worry about giving a rat's arse as to how people view your life once you're dead. Because in death, you should be past caring what others think of you. :) Edit: If you should have children, they can complicate the issue. It'd be hard not worrying that people might hate them through their association with your good self. But still, you'll be oblivious to how they're treated, once you're deceased, all the same.
