Review Detail of Ashwatthama in The Villain's Sword Is Sharp

This is the tale of a yet another sociopath whose whole pursuit in life is mostly strength. And in pursuit of it, He can forsake everything else and do any immoral acts. He feels no guilt at selling off his comrade at the expense of new informations. He feels no familal love either. Although, he is indeed evil, but he feels no need to harm others if it isn't for the sake of benefit. He also has a set of hobbies, such as reading for peace of mind. The power system is quite similar to Gu system from "Reverend Insanity" with few unique quirks. The plot follows a consistent way with no noticeable loopholes. The side characters and important ones all have a character unique to them, and quite sensible ones too. The plot isn't growing too fast and every action of our protagonist and others is descriptive and follows a logical sense. Edit: One thing I forgot to mention is that most of the side characters are, inevitably, equally or more evil than him. I have yet to see a single saint.
