Anger Management: Creating A Society Of Robots?

I've often heard about people being sent to anger management class, for whatever reason (due to the curriculum ... sometimes it's better not to ask why), and never really gave much thought about it. Until the other day when a guy I know told me that he had to attend such classes by a court order. Well since he wanted to bring it up, inquiring minds wanted to know. Apparently, he came home and found his wife "busy" with another man. My friend, who stands about 6'8" tall and weighs in at about 260 pounds, made quick work of the guy borrowing his bed (and wife). And somehow in the judicial process, he ended up the bad guy for fighting and had to serve a short stay in the county joint, see a therapist once a week for two years, and partake in anger management classes for two years. As for the wife borrower, he filed a claim against my friend and received an undisclosed amount of money ... and yes, the two are still together. But, my point is; Who wouldn't go off the deep end in this scenario?
