According to 95 year old Margot Woelk, in the 2 1/2 years that she tasted food for Hitler he ONLY ate vegetarian food and NEVER meat. As Hitler's food taster she has a VERY intimate knowledge of what he ate. She's still alive,(as of 2013.) She was there. I believe what she says over all of the second and third hand "evidence" offered up by everyone else.
If you want non-fiction about Hitler's diet just point your search engine to Margot Woelk, Hitler's food taster.
Don't know about Hitler's views on animals . . . yet, but I'm thinking that his vegetarian self didn't try to kill an entire group or breed of animals like he did us humans so . . . he obviously treated animals much better than he did humans. It wouldn't surprise me to find that he did "love" animals.
There are billions of good people who eat animals.
There are billions of good people who don't eat animals.
There are millions of bad people who eat animals.
There are millions of bad people who don't eat animals.
Not eating animals does not = good.
Good does not = not eating animals.
Being a vegetarian does not make anyone a good person or a bad person either for that matter. Good and bad has nothing to do with what you eat . . . with the possible exception of cannibals ;)
