Some reviews have been critical of the "Redwall" novels for providing too simplistic a view of good and evil. The characteristics of the animals in the novels are fixed by their species, making them quite "predictable", though there have been a few books, such as in "The Outcast of Redwall" and "Pearls of Lutra", in which vermin have acted selflessly, in one taking a spear through the chest and back meant for his former nursemaid, and in the other saving the Abbot of Redwall from lizards. Another exception is in "The Bellmaker", where a searat strove to start being good instead of evil, abandoning his life of pirating to live by himself. In some cases, different members of the same species possess different moral compasses. For example, the wildcats in the book "Mossflower" each exhibit different characteristics: although Lady Tsarmina is cruel and vicious, her father Lord Verdauga is seen as hard but fair, and her brother Gingivere is kind and eventually joins the side of the woodlanders. As a general rule though, characters tend to "epitomize their class origins", rarely rising above them.
