It's not the movie's fault that a kid did that (and I HATE when people blame movies, video games, music for things people do).
It's the parents' fault for not teaching their kid rights and wrong. On top of that, people just don't go around killing animals like that, there is something wrong with that child too. I don't like censorship.
With that being said, it would be a tough call about eating my own pet if it came down to it. I can't SAY what I would do if I were put in that situation.
I respect your opinion and I agree with it completely! Incomplete/not as thorough parenting is to blame.
Buuuuuuuut. Yeah people do just go around killing animals. I assume the kid was doing it for fun. (though I could be wrong I'll have to go back and look at the original post) This is also often called "sport" which is what hunting is. LOTS of people hunt and they do it for "fun"/"sport" as opposed to doing ti forfood aka sustainance/necessity.
I of course think that's terrible (vegetarian. LOL) but all people are different and there are violent people that do just enjoy running around killing things whether it be bugs, animals, or humans. It's sad but it's true. ;]
Now I have to point out that in my last paragraph that I did include humans. Yes humans instinctually don't like killing humans. You can argue with me about this but it's basic animal instinct. No animal likes to kill animals of its own species. They do it because they usually have to. Though when we get to humans as we have symbolism and an extremely complicated and adaptable thought process the "have to" all depends on their state of mind. Humans can be convinced or conditioned to think that they have to kill something or someone (notice I'm not saying ALL can be. just in general). But we still (for the most part. if you're completely mentally average) at a basic level don't like doing it. There's an immense amount of indescribable pain and loathing that comes into play when a human kills another human.
If a person's brain is wired differently and that base instinct of hating killing other humans for whatever reason doesn't come into play however and a person gets the same rush that some do when they kill other animals then that person does just enjoy killing humans.
I'm sorry this is such a dark post. I just never got an oppertunity to use this knowledge! XD
(If you're wondering no I haven't killed anything (except directly bugs and plants and indirectly cattle, chickens, pigs, and the various seafood my parents have somehow convinced me to try over my lifetime. i learned this in a combination of my anthropology class and history class. :P)
