I have only created Jinns and men, that they may serve Me.
-- Sura 51:56

-- Sura 7:179
It would be no problem to say that all of them were created to worship and serve God, but because they have free will and some or many decided to disobey they will be punished in Hell. But to state that many were made for Hell is an obvious contradictions to the first statement - or else we must conclude that they were created in order to serve Allah in Hell, but this would require a serious shift in the understanding of the meaning of Hell as well as the issue of justice in who is sent to hell.
