There is a thing called "Instinct". No matter where the animal is born and reared, it will follow it's instincts. This includes us. How did the first couple copulate? It's instinct.
The bear - if in a position to hunt down anyone, will not refrain from doing it. Even if it comes to his guardian.
Part of the description read the bear used to play with the family dogs.....
*bears running around playing with the dogs when the bear acidently swallows one of the dogs...
Man: Bad Bear bad. Drop it.
*Bear poops out a dead dog*
Man: bad bear go to your room your grounded.
This is what i imagine.
By nature, those animals are calm. Unless, you infuriate them. And again, they don't get excited that easy.
Polar bears are calm and cautious around humans until they're hungry. Then you're food.
Or, you know, until they get bored. 'Cause they hunt for fun, too.
The only thing left to do is ride them into battle.
The only thing left to do is make peace with the deity of your chosen faith. For the end is nigh.
Omnes laudo infinitum-ursa I, for one, welcome our bear overlords with my horribly broken Latin.
