The prototype of the rule creator, but not the only variety as we shall see, is the crusading reformer. He is interested in the content of rules. The existing rules do not satisfy him because there is some evil which profoundly disturbs him. He feels that nothing can be right in the world until rules are made to correct it. He operates with an absolute ethic; what he sees is truly and totally evil with no qualification. Any means is justified to do away with it. The crusader is fervent and righteous, often self-righteous.
