Nonsense. The author is trying to rationalize his own intellectual dishonesty.
The unfortunate truth is the killer writes better in english as a second language than 95% of native english speakers.
The guy is a "Bond villian." Deal with it. Trying to pretend he's something he's not only degrades the authors credibility.
Anyone who presumes to evaluate the murderer without reading his self confessed raison d'etre is worse than a fool.
The category of "Evil" is something that gets short shrift.
I'll admit I don't know how to grasp it.
