Allah the sadist. He punishes unbelief with eternal damnation though he is the cause of unbelief. Islam could not exist without the disbelievers.
2:6 As for the Disbelievers, Whether thou warn them or thou warn them not it is all one for them; they believe not. 2:7 Allah hath sealed their hearing and their hearts, and on their eyes there is a covering. Theirs will be an awful doom.
