well, prison is a pretty bad environment.
you can see same results in farms where harmless chicken start murdering each other for no reason to the level where you even expect few percent of your stock to kill each other.

But actually there is one prison where men live pretty peaceful life and rub each other shoulders cant give a link because I saw it on TV
probably it will be this one
