My question is, in this novel Buddhists are treated as nefarious individuals, arrogant and self certain yet duplicitous and controlling.
This is not the first novel I've read like this. I've read dozens of wuxia and xianxia novels over the last decade, and almost uniformly Buddhist sects or cultivation are treated as both insanely powerful, and insanely untrustworthy/controlling.
To be fair, I'm from America, the knowledge I have is very much only Americans outlook of Buddhists, in general we perceive them as kind, benevolent individuals with a high spirituality and possible martial ability. Seeing this is fascinating.

我的问题是,在小说中佛教徒被看成了邪恶的人,傲慢,自以为是,但又两面三刀,控制欲强。
这在我读过的小说中已经不是第一次看到了。我在过去十年里读了几十本武侠/仙侠小说,几乎清一色地把佛教教派或佛门修行看成既强大无比,又极不可信,控制欲极强。
公平地说,我来自美国,我掌握的知识在很大程度上只是美国人对佛教徒的看法,一般来说,我们是把他们看成善良、仁慈的人,具有极高的灵性,可能身怀武功。发现这一点后,我被深深地迷住了。
