Having read it, it’s not quite that bad. The title is somewhat tongue-in-cheek and the author’s argument, while made annoyingly difficult to parse by the conceit of speaking as a devil and the nineteenth century language, seems to be that empathy as a boundary-less emotional fusion with a suffering other, is a debasement of compassion, which maintains enough distance not to drown in the other’s misery. That’s a misunderstanding of empathy and a strawman but not encouragement to harden oneself against the suffering of others.
