English is not the first language of the Inuit people, most can speak Inuktitut and English though. Catch was probably a "suggested" term by the kalunat(white man) as more refined and "pleasing" to the ear. Or maybe it is meant to suggest catching the spirit of the animal, for which they have much respect, regardless of the way it was killed or taken.
I am sure the boy took great delight in feeding his family, a proud tradition continues and I have no doubt any of that animal went to waste. The satisfaction comes from providing for the family, not the bloodthirst that some are trying to focus on here. Most people are ignorant of survival and sustainable living due to living comfortably in society, up on the tundra it is not so easy.
So if you want to judge, put on a pair of sealskin boots and caribou parka and try living off the land above the tree line for a couple days. Until then leave the boy alone unless you have something positive to say, and keep the ignorant and racist comments to yourself.
Rant over.
