Black bear attacks are incidental and rare, usually associated with a surprised bear or a bear with a cub. Simply being noisy while walking through woodland is usually enough to ensure you never even see a bear.
I provided three current examples of black bear fatalities, two of which were apparently unprovoked and one occurred even in the presence of dogs. There are more. IIRC attacks are increasing as well, more human exposure and bears adapting. I would argue it's attacks by big domesticated cats that are incidental and rare. One is wild, one isn't. I also don't find predatory feeding instincts to be a behavioral analog to your example of hierarchical strife, but maybe that's just me. Competition != food. As a fellow owner of that breed of cat, my experience has been different. Quite a mouser and very at ease around dogs, very intelligent, but overall a big goofy baby. Bengal tiger not found, no fisher cat here either. I think that example does apply to mustelids though. If fishers and mink and weasels and such got as big as bears we'd all would have been wiped out long ago. Those things
destroy.
