We have little evidence that they used the dissociation trick. But I think it is not really required anyway. Most of us don't need it to get by with our daily lives. And it's far too simple to demonize the villains just by saying they used this trick.

Similarly, to be able to silence our cognitive dissonance when we find out that the people around us and the system we live in have dark sides to them.
