Bond also stated that "the homicidal impulse may have developed from a revengeful or brooding condition of the mind, or that religious mania may have been the original disease but I do not think either hypothesis is likely".
Bond konstaterede også, at "den morderiske impuls kan have udviklet sig fra en hævngerrig eller rugende tilstand af sindet, eller at religiøst mani muligvis har været den originale sygdom, men jeg tror ikke at begge hypoteser er sandsynlige".
