Listen closely and see if you can honestly and effectively dispute the answer. Knowing it is not the Holy Ghost by any stretch of the imagination, who is it then? The answer is compelling. There is some other evidence below to consider as well.
Exodus 12:23,29, Luke 8:29-31
So Abaddon is either Christ himself or an angel directed by Him to destroy, but it is not the Holy Ghost. Jesus, himself, could have sent "Legion" into the Abyss or Deep.
