I had already read the 3 books of the 3-body series in its English translation, and it seems to me the author was very much storied in the human ruling systems impositions and manipulations on people leading to their tragic outcomes. There were choices but so little room for free will. Humans were the most dangerous, because unlike the aliens, we were adepts at lying to ourselves and to each other, and also in being deceived, as a social mass, and this was our the most terrifying ability for the aliens who had evolved to not be able to do this.
