That is a ridiculous comparison. Deer do get eaten by bears, even if it is rare. It's a part of nature. People don't typically get eaten by bears. That's not part of nature. It's not at all saying the same thing as shooting your wife...because (a) you aren't going to eat her and (b) she doesnt have the real chance of getting eaten by a bear. Your analogy of his analogy is terrible.

This is not how evolution works. While that may happen at some point, it wouldn't be because people stopped eating meat. Evolutionary changes ONLY occur through genetic mutation. People's altered behaviour does nothing to the gene pool. If every single person stopped eating meat, it would not alter our DNA to remove the aspect of carnivorism (is that a word?). It would simply be a behavioural trait that people learn. People would still be born with teeth and digestive systems that are able to digest meat. Stopping the consumption of meat would not alter the DNA in any way and therefore would not alter humans ability to consume meat. By simply choosing to not eat meat, we would not evolve into a herbivorous species.
