I would be a bit more scared of the bear.
If I had to choose, I would be in the woods with the man.
Yes, the man could be a rapist, and the bear isn’t in to that, good point. If he was a rapist he might not kill though. With the bear it will either run away or hurt you really badly or kill.
The probability of the man having bad intentions is low. You have just said a man, so statistically, how likely are they to be violent? Whilst a man is stronger than me generally, I know how to tackle one, and would kick and bite the right place. I do not know much about bears but I cannot negotiate with it, I cannot outwit it verbally and a bear can outrun me and climb trees and are powerful, I think.
Question, what about a baby left with man or bear? What now?
