One of the more ethical questions of the Chrono series has been the nature of Lavos; is he a mere thoughtless parasite -- a scourge to the universe -- or perhaps he is sentient, with the capacity for evil as judged in human light? At first glance, he seems inherently evil, raising intelligent creatures for harvest and destroying a vessel of life. The question runs much deeper, however; is this a meditated evil or the base instinct of a hungry, gargantuan parasite? This question is looked into by myself and five other members of the Chrono Compendium. It can be read, here --
