Art is the process of evoking pity and terror, which is not abstract at all but very human. What the self-styled modern artists are doing is a sort of unemotional pseudointellectual masturbation . . . whereas creative art is more like intercourse, in which the artist must seduce -- render emotional -- his audience, each time.
Monsters remain human beings. In fact, to reduce them to a subhuman level is to exonerate them of their acts of terrorism and mass murder? just as animals are not deemed morally responsible for killing. Insisting on the humanity of terrorists is, in fact, critical to maintaining their profound responsibility for the evil they commit. And, if they are human, then they must necessarily not be treated in an inhuman fashion. You cannot lower the moral baseline of a terrorist to the subhuman without betraying a fundamental value.
