For the foregoing reasons, we conclude that torture as defined in and proscribed by Sections 2340-2340A, covers only extreme acts. Severe pain is generally of the kind difficult for the victim to endure. Where the pain is physical, it must be of an intensity akin to that which accompanies serious physical injury such as death or organ failure. Severe mental pain requires suffering not just at the moment of infliction but it also requires lasting psychological harm, such as seen in mental disorders like posttraumatic stress disorder. Additionally, such severe mental pain can arise only from the predicate acts listed in Section 2340. Because the acts inflicting torture are extreme, there is significant range of acts that though they might constitute cruel, inhuman, or degrading treatment or punishment fail to rise to the level of torture.
