Lu Tu never intended to kill him; he needed to leave one alive to extract information, since he didn't know enough about Xu Jing.
He hadn't asked Nangong Huiyu too much about Xu Jing before, mainly because according to the White Lotus doctrine, the two should have a marriage contract, so Lü Tu deliberately avoided the question.
