The english would have gone on the crusades with or without christianity, it was in their nature.
They might not have chosen to head off to Jerusalem though. It was considered to be the duty of christians to protect this city for whatever reason. If you can believe that, then the plundering was just an added benefit. If religion played no part whatsoever, it would probably be easier to plunder somewhere a bit nearer.
