Betrayed just once, hostile forever

Here's a report on why the men turn hostile in society. First men are betrayed, rejected and humiliated as boys by the society, then when due to obvious reasons some of them turn hostile, they're only blamed again. Excerpt:

"A new study seems to have confirmed the link between social exclusion and aggression by showing that people who feel socially rejected are more likely to see others' actions as hostile.

What's more, they are more likely to behave in hurtful ways towards individuals they've never even met.

For the study, lead author C Nathan DeWall, PhD, from the University of Kentucky, conducted four separate experiments with 190 participants, all college students. In one experiment, 30 participants completed a personality test and were given bogus feedback about the results."
