Two things...first, I liked the title itself...you could submit a Philosoraptor with just that! Second, I think that there are things that you shouldn't do (Ten Commandments, Seven Deadly Sins, etc.), but we're all sinners by birth. If you repent, know you did wrong, and try to atone by living right from this point on, then you'll be good. I don't really buy into the whole "heaven and hell*" thing anyhow, I think that is just a form of cosmic carrot & stick. I'm more of a "be excellent to one another" type.
*Ironic, because I'm currently listening to that song by Black Sabbath as I type this.
