None of what you say explains what Raphael describes the vampire ascendant is. He clearly states that Casador will have all the arousals of men return to him meaning that he will be a LIVING vampire with the appetites and feeling(?) of men. Basically a "superman" with vampire powers. The lore you state is a description of a true vampire, not an ascendant. There has NEVER been a vampire ascendant (at least that what the game states) before according to Raphael, because the ritual (besides being diabolical) is almost impossible to perform. Casador have been at it for nearly 200 years, collecting the souls, getting all the pieces in place.
So it really is all speculations on our part, for we have no concrete description as to what the ascendance does to a vampire.
Well, as far as i concern the ascending was a good ending. And i can't even believe that there are people who is actually thinking that letting 7000+ vampire spawns to go wild/free is a "good ending". But, when after ritual he began to tell how he wants take over the world (this guys many times said how much he hate when powerfull dudes dissing around the small folks), i remembered that oh yeah, this is is Hell's ritual made up by Mephisto, so ofc it has fine print details to it, as for example pulling the "alignment"/soul of the ritual user closer to Hell, it could not been any other way. So Dunno, i would say it still better that the alternative, at least its more climatic.
