Why should any torturer feel guilty?

The attempts to justify torture rest on some tacit philosophical assumptions, which I reject one by one. These assumptions rely upon the presumption that no singularity differentiates one person from another. Were torturers and those who attempt to justify them right, the categorical difference between objects and persons would be obliterated. Torturers also ignore the absolute moral right to self-defense of any person as a singular human being, however atrocious. In light of the principle that any person is a singular human being, I clarify in detail that inflicting torture is absolutely immoral. Allegedly, the function of torture is interrogative or inquisitive, but actually it is penal, for which no justification exists. Since torture has no moral justification, torturers do their best to hide their identity, even in cases in which they spread the word about the torture and the methods employed. Every attempt to justify torture is a case of self-deception or openeyed deception. This clearly demonstrates that torturers cannot ease the burden of guilt resulting from their atrocious deeds. Since torture cannot be justified, torturers should feel guilty. Because of their guilt, they strongly attempt to conceal their identity.
