The man who, whether in adult life or in boyhood, has submitted to this sort of thing, is filled with anger, which turns him either into a furious rebel or into a man with a ferocious desire to torment other delinquents when his turn comes. The latter feeling can be justified as moral indignation, and the man who feels it never realises that it is really a desire to inflict on others what he has been made to suffer himself.
