Okay, this getting a little out of hand I think. This reply is at pretty much everyone, and is going to be super generalized.
All of the cases where things like cats or apes have done this to people, there were extenuating circumstances. They thought they were playing, and did not proceed to eat the person, or were starving because the person could not afford their care, so they did eat a person they would not normally have eaten. Specifically with apes there were generally problems with a social interaction that would not have been a thing for us, and was for the apes, and in many cases there were other apes involved that pressured the pet ape's actions. There can be NO DIFFERENCE between today and yesterday, except TODAY is time for the bear to eat you, when yesterday was not.

"Grizzly bears are mainly solitary and territorial, except for mothers and her cubs or when a plentiful food source is discovered. Grizzlies are known to congregate at rivers with many fish and at improperly fenced garbage dumps."
See? Territorial.
A bear will kill his own babies to mate with the same female again, which makes no sense, and mothers will kill their babies if they wake up too hungry, which I know is so they can survive to have MORE babies, but I mean even the "mama bear" stereotype does not hold true in every circumstance.
I'm not saying that bears do not have their own place in the ecosystem. I don't by any means want them hunted to extinction or anything like that. And I'm not saying that I want them to be pets. This isn't an anti-bear crusade. There's lots of things that don't make good pets, but I still can appreciate them, and usually like them. I just don't think bears are something that should be romanticized, when I can't find ANY redeeming qualities that other major predators have. And I used families as examples a lot, but it's not the only redeeming quality there is, and other predators have them. Bears are just big mindless monsters out for themselves, and not very efficiently at that. Like it seems like I am ONLY applying human morals to an animal, but I don't think normal rules for NATURE applies to them either. How can something that destroys its own genetics for its own, singular, limited life be a successful species?
If you want to like them FOR those horrifying reasons, awesome. Good for you. Otherwise, I don't get it, or condone it, but I obviously can't stop you. Do what you want.
P.S. Birds? LOL XD How'd this happen? *is actually the owner/head admin of a Memo on Pesterchum called #BLuE_FOOTED_BOOBIES if any of that made sense to anybody. Just thought it was oddly relevant*
