Except, have you read his holy book? He's doing exactly as commanded, that's why his imam finds it hard to protest. The whole idea that "jihad" might mean something else than murdering and subjugating non-believers is an invention of an 11th century scholar, with no basis in the Koran.
There's a large amount of people who self-identify as Muslims yet find jihad to be abhorrent. That doesn't make the Koran any better, though -- it just makes those people not evil, unlike what their holy book demands. You're confusing the Koran with the Bible -- the latter is a large collection of often unrelated works, with hardly any internal consistency. Try for example Psalms 82:1 which says "Jahveh sits on the court of the God of Gods, and passes judgmements to other gods in his name." -- it's really interesting how various translations try to wiggle this statement around towards the current religion. The Koran has no issues of this kind: it's a highly consistent work edited by one man (Uthman) (ok, ok, plus a bunch of scribes doing his bidding). It does deliver a consistent message -- and I really don't like what the message says.
