Here's an interesting find:
Abuses at infamous Florida boys reform school even more widespread, report says - U.S. News
My theory is beginning to take shape--
I suspect that SJs and NFs are the types most capable of demonizing someone we perceive to be bad, which is why, even though we are normally good-natured and cooperative, at our worst we are capable of tremendous evil (i.e. NF Hitler). We rationalize away our guilt by telling ourselves things like, "He is bad for worker moral; he broke these rules" or, in the case of this boy's home, or Hitlers's anti-semitism, "These people are bad through and through--nothing is ever going to change that." I now suspect a lot of Dickensian bad guys were SJs or NFs--as well as Jane Eyre's old school master.
SPs and NTs, on the other hand, tend to be grimly realistic about their foes, and at their worst, become cynical or apathetic about evil, even going so far as exploiting it for their own ends (i.e. NT Stalin.)
