I think the reason some of us have difficulty with a bear's death moan is that it can sound almost human-like. It's only normal to identify with that and perhaps feel a connection. Most of us (I assume) believe that the experience of dying...that time where life declines quickly and then ends...is uncomfortable and a struggle. I think the 'death moan' is a vocal indicator of that final stress, just before death ensues.
The Bear stops Knowning that what death all about we stop knowning,,,,
