Will the Islamists kill Islam?

[GUBU]

So we've seen Daesh publicly butcher anyone in their territory who doesn't agree with them, destroy art, commit torture etc.
Personally I'm struck by the similarities to the actions of the Puritans during the Interregnum.
Since the restoration Christianity has never really been on the same footing in Britain, could the same happen to Islam?

Darwin had more to do with killing christianity in England than puritans during the inter-regnum.

By Victorian England the position of most demoninations was that he was both the watchmaker who made the universe and the regulator in the system keeping it ticking. That's one of the reasons why On The Origin Of Species tackles Paley's watchmaker argument first. After Darwin it was possible to think of the universe having no gaps in which god could exist.
