Does that really matter? Granted, I suppose it wasn't a PERSONAL VENDETTA, but he was honed in on destroying Guybrush from the get-go. After that, we could say it's just an extension of that first job, a matter of personal pride in his work.
Also, he was pretty happy. He was in a great mood, and it was just one of those good days to be dead.
