Has anyone rear fr. Jose Antonio Fortea's summa daemoniaca?

If so, is it doctrinally sound? Some of it seems confusingand perhaps incorrect, or I do not properly understand Spanish, but here is an excerpt in English from http://vivificat1.blogspot.com/2012/01/what-is-demon.html?m=1

"There were phases in the angelic psychology before they turned into demons. These phases didn’t take place in our material time, but in the aeon. (What’s this aeon will be explained later in this work).

Since they took place in the aeon, these phases would seem to us human beings as having occurred almost instantaneously. However, what to us would seem so brief, to them it was a long time indeed. The transformation phases from angel to demon were as follows: First, they doubted; a doubt that disobeying the Divine Law was better than not. At the moment in which they voluntarily accepted the possibility that disobeying God was an option to consider, they sinned. In the beginning, accepting this doubt constituted a venial sin which little after little evolved toward grave sin. Yet in the beginning, none of them during this first phase were willing to move away from God, not even the devil. That happened later, when what they had chosen with their will began to settle into their intellects, despite the judgment of their own, very same intellects reminding them that such disobedience went against reason. But their wills kept moving away from God and as a consequence, their intellects began accepting as true the evil thing their wills had chosen. Their intellects continued to consolidate their error. The will to disobey continued to consolidate, becoming deeper in its determination; their intellects continued to seek more and more reasons to increasingly justify their stance. This process led them in the end into mortal sin which took place at a concrete moment, [in time, in the aeon] through an act of their will. In other words, each angel reached a moment in which he not only wanted to disobey, but also chose to have an existence outside the Divine Law. It was no longer that their love for God had grown cold, that theirs was not a minor disobedience to something predetermined that was hard for them to grasp, but that in their wills appeared the idea of a destiny apart from the Trinity, an autonomous destiny."

I'm not reading a lot of the general teaching that angels would not serve or help mankind because the angels felt humans were essentially too limited to be of much use, only that the angels who would become demons sinned like humans do and that is why they're demons.
Plus, fr. Fortea is a Jesuit, and I am alway extra skeptical of Jesuits. It was, after all, a Jesuit who put forth hell as a limited time punishment, so imo, it looks like the Jesuits (and the rest of the human race) are suffering the same intellectual war amongst themselves that fr. Fortea describes here....gets me thinking.
Anyway, I am curious to know if anyone has read it. and if so have they found anything opposed to tradition in it?
