Hell isn't scary

[Angrboda]

No, I said god invented sin.  Unbelief is an example of sin, but isn't the entirety of sin, correct?  Sin would also include violating the commandments, and other things, such as premarital sex, engaging in homosexuality, etc.

Wrong, Unbelief IS sin, the acts that you mentioned are ATTRIBUTES of sin, in other words, by committing those acts, it shows that you don't believe.

For example, say there is a door, and I tell you not to open it because there is a dangerous animal on the other side. If you proceed to open it anyway, you obviously didn't believe me. Therefore it was your unbelief that caused you to commit the act of opening the door.

Bullshit. The cause of you opening the door was your desire to open the door. If you didn't desire to open the door, you wouldn't open it, animal or no. You're just making up clever word play to cover an empty theological concept.
