Looks like they had a good go with a machete (o several machetes) - then a few blows from sticks for good measure. Then they drag him around by a rope round his neck, but it's kind of hard to strangle a guy when he's already dead. And ditto about "learned his lesson" - I doubt it, I suspect his capacity to absorb new information and learn from it had declined to zero.
