I would recommend the following (audio only at the moment): What Is Torture? Our Beliefs Depend In Part On Who’s Doing It.
The piece is about social science research on torture and notes, among other things,
1. Humans are likely to define “torture” differently if it their group doing it versus when other groups do it (spoiler: they give their own group a pass).
2. Even once the reality of the torture is clear, if done by one’s own group, the effects will be minimized and/or the actions will be rationalized as necessary.
(NPR usually has a transcript up by afternoon/the next day if listening isn’t possible).
