The dad shouldn't have to pay for the need for psychologist/s, et al to assist his son. Maybe a lawsuit is needed to help RIGHT this WRONG! If not, people need to step up to fund assistance for his son and to help repair the dad's fists and feet, if needed. Thank God this man arrived home before any further damage to his son. To me he deserves Time magazine's "Man of the Year"!I don't know if I could have shown the restraint to stop before killing him. I commend the father for being able to. Had he went all the way on the sick pervert, (and IMHO, had every right to) he would have been thrown in jail. He may have beat the charges on a temp. insanity defense, but look at the legal fees he would have incurred. Now he's faced with trying to mend the emotional damage that his son will almost certainly suffer from.
Everyone needs to be vigilant in who their kids and grandkids associate with.
