Notes on The First Epistle of St. John the Apostle (Author Bishop Richard Challoner (ed.))
5:19 And the whole world is seated in wickedness: That is, a great part of the world. It may also signify, is under the wicked one, meaning the devil, who is elsewhere called the prince of this world, that is, of all the wicked. John 12.31.
