Killing animals for food? If you are someone who regularly buys supermarket meat, intensively reared animals which then spend hours being crammed into crates to an abbatoir, I think it's a bit rich to criticise someone for using an age old quick hunting technique to kill food for supper. And make sure you never cook game.
And what about the love and pride between father and son? Real love. I have seen cowed scared abused children, and whereas it is impossible, and wouldn't be right, to condone the rough justice, that boy knows he's loved. By a father who supports and agrees with a greater level of education than he had.
It wasn't the swift bare knuckle fighting that did for him - whatever you feel about concensual fights between adult men, it wasn't, at least, gang warfare. When he said it was done with, he meant it. The machete attack, on the other hand, was completely outside that 'code'.
There was violence shown, but many other things besides.
People seem to see what they want or expect to see.
We met a traveller family on a campsite - the kids all sparrred with each other all the time. Including the girls. Them to my horror, DS was invited to join. But an older boy was really responsible, would not allow two inexperienced boxers to spar together because they wouldn't have enough control, taught DS and his friends how to do some moves, but made sure that no one actually got hit.
And as Troisgarcons said, all the kids had social skills and politeness that would have out many a typical teen to shame. And the older kids, boys and girls, looked after all the younger ones, plus new little campsite friends with care, sensitivity and humour.
