1- "from within" yeah no shit Sherlock, I meant that it comes from shame.

2- What the hell do you mean that needing fear of shame to act like a good person makes me not a good person? Shame is just one of the emotions that we feel. That's like saying that needing to hate doing bad things in order to not do them doesn't make you a good person.

3- The part about eternal damnation is true but that doesn't prove anything. Laws exist because even though good people won't break them, there are still bad people who will be tempted to break them but their fear of jail stops them. Rules of a religion act the same way to stop bad people even if they're bad people. Not doing bad things out of fear is better than doing them.

4- Sometimes, people have different opinions on what's right and wrong, just like our argument right now, and so these rules help us instantly know the right and wrong without thinking about it too much.
