Iamon lyme: I mean choice in the sense of before we could rationalise, see the difference rather than just reacting unconsciously.

"The effects of evil aren't limited to us, even though we are responsible for letting it in."

To a certain point depending on age.

" Natural selection didn't sin, we did. But if you open a door and let smoke from a pulp mill in, you won't be the only one (or only thing) affected by it... the smoke will get on and into anything it comes in contact with."

The ripple effect... yes. But as the smoke getting into everything.... that is where free will really comes alive. The ability to step back and be as it were an unmoved mover (it's an old Greek term for the essence of being.. ie God)

"If you assume evil bugs were here before the problem began, it's the same as assuming nature cannot change. Nature can (and does) change."

Our genetic structure proves bugs were around, some helped to form of immune system and helped us to evolve... and yes nature does change. Dinosaurs are alive no as birds are they not!! ;P
