Killing the bear would be the "price" I would choose to pay.   It wouldn't make me happy to kill the bear,  but any pain it caused would be nothing to the pain of seeing human being needing help and denying it.   We have horns to scare the bears away from our property,  but if the horns don't do the trick (sounds loud enough to wake the dead)  I am not going to watch a bear kill a neighbor, stranger or mortal enemy much less a loved one,  and chalk it up to "the price ya gotta pay."
