I guess the author of this video only read "The Prince" and none of Machiavelli's other writings. And the author added some of his own opinions, like the criticism of Jesus, which Machiavelli never said. "The Prince" simply explains how to be a successful ruler without any moral commentary. Machiavelli addressed moral questions in his "Discourses on Livy" which can only really be understood after reading Livy himself. This book would have produced a rather different video, probably with an emphasis on religion as the most practical means of supporting goodness.
