Sadly Mr Dawkins, it seems to me, has not been properly immersed in the wonderful teachings of God. God forgives all people, so although old Richard may not agree that he will be forgiven or even believe he will, God's amazing grace will mean he is saved and will go to heaven!
Something that isn't there is incapable of forgiveness. Even within the requirements put forth in the Bible forgiveness requires asking for it. So either way the answer would be "no". An even more relevant question would be if "God" is guilty of existence would I forgive him? The Bible is littered with atrocities he has either commanded or condoned. As a fictional character I still consider him to be the main antagonist within the plot.
