I've written before on freewill here.
I'm taking a different angle here, however, namely looking at god's wrath. Of course there's the instance in the bible when god hardened the pharaoh's heart, and that clearly is a case when he interfered and removed freewill from someone (Exodus 7:13, 22; 8:19). The pharaoh was evil so god intervened. I have no problem with this, but if you claim god grants freewill then this is a violation of that pact.
But let's discuss the Great Flood. Obviously this never happened. It's just a regurgitation of the Epic of Gilgamesh, probably used pathetically to convince believers that their god could smite them at any time. Here is an excerpt that explains why god brought the rains:
“The earth also was corrupt before God, and the earth was filled with violence. And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth. And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth.” (Genesis 6:11-13)
So, how is this freewill? You create humans, give them freewill to act as they want, then when they do and you disapprove you wipe humanity from the face of the earth? Granted, these people may have been pure evil, and they may have deserved death for their indiscretions, but I didn't set the rules or parameters. Freewill isn't free if the threat of murder is lingering over the prospect. By killing everyone, god is in effect, taking their freewill.
A Christian may argue that these people had freewill until god levied his punishment, but I would argue god kept them from doing what they wanted. He also kept humans from dealing with their own problems, and from that moment on, freewill never exists. If you know god will kill you for your actions, and that killing could/would come at any moment, true freewill ceases to exist.
There are so many problems with the Great Flood lesson, and there are plenty of instances in the bible where freewill is infringed upon, but believers refuse to take their god to task. Why? Fear. And by being afraid to question god, you have lost your freewill.
