I have a vegetarian friend that hunts, in know kinda weird .He would give the meat away, he loved to hunt but didn't like meat. I on the other hand eat meat with almost every meal. We hunted together for years, he killed slot of deer, but he didn't see any more deer or get scent busted any less than the rest of us. We even discussed the whole meat eater thing and came to the conclusion over a few years that it made no difference.
With all the roughage he ate, his farts would dang near kill ya.
If I see a grizzly eating berries and looking content, I still want assume he won't eat me.
