So if I decide to slather myself with bacon grease and lay around in known bear areas on Kodiak the bear that comes snack on me should die?  What if I was just holding the bacon on my lap?  Brought it into my tent with me?   Cooked it on my cookstove?  Handled it that morning but didn't actually bring any with me?  Rips open my Winnebago while I'm cooking bacon?  

Or perhaps this:  I crawl into a wolf den with pups and the mom chomps me.  How about if I just reach my arm in?  Sit right in front of it?  10 ft from it?  20 ft?  A half mile?

Kicked a baby moose and momma stomped me?  Tried to pet the baby?  Got between baby and mom?

It's a gray area and I think we need to consider the circumstances.  Did we do something incredibly stupid to lure the animal or back it into a corner?

So no, I don't think they "always need to die".
