Why is the sin nature inherited?

[Cinjin]

If Adam and Eve were able to fuck up that badly, they were hardly created perfectly. Perfect creations don't fuck up; can you imagine if I created a perfect car that broke down in a matter of days?

not only did A&E mess up right away, but the VERY first man ever born on this planet was a murderer. I'd say that makes their god either a supreme fuck-up or an exceptionally sly bastard bent on making mankind evil. Hell, if their god was real, I'd say we manage to do some good on this planet DESPITE him not at all BECAUSE of him.


Or maybe their god just knew that not only was his garden never going to be able to feed 7 billion people, but that he was going to want fuck with us a bit for his own amusement. It's such a poorly written stupid-ass story.
