It is just in our nature... 
Right Boo-Boo?
Yeah, Yogi, especially when there are delicious hikers in the area like that bunch over there-- 
Let's go eat 'em while they think we are cute and fizzy!
It has always been a puzzle to me that animals that are so large, strong, and vicious can appear so cuddly and adorable.
Why do bears have to be so cute?

Dunno. Used to live cheek-by-jowl with Black Bears in extremely northern California, up on the Smith River. They'd get into our garbage cans like dogs would. You'd hear a big, metallic ruckus outside, go out with a flashlight and a rifle on your shoulder and see a big fuzzy brown fanny sticking out of the overturned can. I'd yell at them to go away and they would, taking their time. I'd have to go clean the mess up in the morning. Later- I had to live even closer to them. Beyond the foregoing, they didn't give me a bad time and I didn't light them up. They were kind of annoying at times, but I liked being around them at the same time.
And good to eat.
It makes their prey feel better.
I don't know. Perhaps you should ask Timothy Treadwell. Oh, wait...
