His motive was that he was the only one who actually never murdered someone
*SPOILER ALERT!* If you are referring to the Justice Wargrave in "And Then There Were None", his motive was simply to bring justice to the murders where the "murderers" had gotten of Scots-free. Even though some of them didn't actually kill someone, he felt a need to kill all of the people that had killed someone and gotten off free. However, he also was motivated by the morbid and sick thought of wanting to commit the perfect murder: one where no one could ever solve it.
His motive was to get rich, become a governor of a colony and to find a route to Asia. None of it did he successfully accomplish.
