>>What if the Bear shud again change it's mind!? To again go back on the Attack!?

Why would it do that? A bear will only attack a human for one of two reasons - it's defending itself or its young against a perceived threat, or it's looking for an easy meal. If it thinks you're a threat, then attacking it is going to tick it off big time. If it's looking for a meal, then it probably thinks you're dead and pointing out its mistake is not the wisest move.

>>Additionally, the Bear knows his initial victim is wounded. He (or She) could wait things out from nearby, -or move in to try to more actively Finish his Victim Off!

Bears don't much care whether you're wounded or not. If it thinks you're wounded, that's only a good reason to move in and finish the job. If it wants to finish you off, it'll just walk in and do it.

Black bears that kill humans for food (rare, but it does happen) will usually treat them like any other animal they kill - they'll drag it around in the dirt, then leave it for a couple of days until it gets nice and gamy and softer to chew. Often, they'll bite a chunk out of the buttocks to tide them over. As far as I'm aware, there's only ever been one recorded case where a grizzly killed a human for food - all the other attacks have been because the human startled the grizz, got between a mother and her cubs, or was just too plain stupid to realize the bear was getting upset with them. And even in that one case, the victim was an amateur nature photographer who was probably taking care not to make a noise - the last thing you want to do in grizzly bear territory, since it greatly increases the risk of surprising one.
