There is free will.
But then you KNEW i was going to say that.
I assume that there is free will, because if there is NO god then there can be nothing that causes people to do things other than their own desires, and if there IS a god (or several) then what would be the point of a creation in which there is no development?
If there is NOT free will, then we are all just the daydreams of god.
Either way - if we assume that there is free will then people can be held accountable for their acctions - oterwise they are able to say "god made me kill and eat those people"...
The choice to act or not act in any situation HAS to be the begining of all morality.
