Take it from the experts.

The Sociopath Next Door.

So far, this is such an antagonistic book. But I suppose, given the "type of people" the text is about, and obviously, who the author's attempted attacks are directed to, it's (and this without trying to be or sound condescending) humorous.

THUS, absolute irony.

Now, any specifics?
Well, the listed "tips" to "arm" oneself against the "evil" the subjects are could do. That is, disregarding the religious tones against Freud's theories on the superego, which has no room for emotions but functions purely on human reason. The author decides to disprove these theories with biblical examples as evidence... I mean, really. It's funny.
