None of this is scientific. It's only one man's observations, but you may find it interesting, or it might be the basis for a scientific examination of the subject. Anyway, here's what I've noticed. Guilty men are quick to assume the guilt of others. This trait seems to be part of a broader tendency.
Guilty men tend to see the worst in other people and to exaggerate the worst parts of other persons.
The second thing that I've noticed about guilty prisoners is that they favor severe punishments. They don't want to be punished themselves. They want their fellow prisoners to suffer. This trait seems to be part of a broader characteristic. Guilty men, more than those who aren't guilty, want others to share their misery.
