Throughout the multiverse, any practice by which severe pain and/or suffering was inflicted on a being, whether physical or mental, was considered torture. Torture was used for such purposes as obtaining from them or a third party information or a confession, or as punishment for an act an individual had committed or was suspected of having committed. Another motive was pure and simple revenge. Torture also served a function as a way of intimidating or coercing individuals, or for discriminatory reasons of any kind. Occasionally, torture was the adverse byproduct of either medical or scientific research, studies, or procedures, and usually occurred without the expressed consent of the victim. Oftentimes torturous methods were initiated by the directives of heads of state, though other individuals or groups were capable of inflicting torture for the same reasons. Since Force-sensitives can sense the reactions of loved individuals in such extreme situations, torture can be used as a means to manipulate them, even from a considerable distance. However, another motive for torture was simply for the sadistic gratification of the torturer. The Combine's reason for the torture is to force a person to forget everything about their old lives before their capture, in other words, they force a individual into a state of amnesia.
