Well, in the wild they do only kill the sick and the old,....
This is where you started. Now you're at "easiest meal."
Frequently the easiest meal is a prime, healthy critter that happens to be in the wrong place at the wrong time. The "sick and old" only is a myth. A few wolves are capable of taking down any ungulate in North America and do so on a regular basis.
I'm not anti-wolf per se, but the truth is the truth. Wolves and grizzly bears don't mix well in many places - sad but true.
