Review Detail of Bolo_Johnson in Necromancer Emperor

Is he a villain or a anti hero, because I prefer a villain that is willing to do whatever it takes and is apathetic that doesn't care people lives, and he hope there's no romance/harem it ruins the stories and doesn't make any sense that's why I love other villain protagonist web novels such as reverand insanity The ruined death knight Alien evolution system Cursed immortality Sadistic player in a fantasy game world Soul of negary Ect.
