It is usually those who lack any measure of self-control who crusade against external evils. They attempt to calm the storms of their internal chaos by controlling and orgainzing their environment. Anyone with obsessive cleaning habits and frequent uses of "may I" and "if you please" likely has corpses buried in his backyard.

The emotionally stunted usually end up becoming "reformers." Smash open a head of any reformer, and you will find head full of evil ideas to destroy a civil society.
