Actually I think you may have it backwards, don't you see it is Islam that will tell him to indeed commit murder of that neighbor.
Like Christianity, Islam has a whole lot of interpreters.
Some would say Islam and Jihad are compatible.
Some would say it's not.
Keep out those who believe in Jihad, and allow in those who don't. That's pretty much what Visa screening is supposed to do (although they screw it up at times).
