The other exception to the rule regards dealings with masochists. A masochist derives pleasure from being hurt; so denying the masochist his pleasure through-pain hurts him just as much as actual physical pain hurts the non masochist. The story of the truly cruel sadist illustrates this point: The masochist says to the sadist, "beat me." To which the merciless sadist replies, "NO!" If a person wants to be hurt and enjoys suffering, then there is no reason not to indulge him in his wont.
