Are you a pantheist? If not that's a refutation of your God argument right there in my view. If so it would be an internal contradiction as parts of the universe are more merciful than the whole indifferent universe making your God less merciful than things Islam generally doesn't want worshipped (such as a parent for example) in my view.I know. But thanks.
And if your God argument is refuted (which at this point I believe we can successfully say it is) then your God argument is logically unsound or put another way using shorthand, we may say your argument for God is illogical.
