That's a gross misrepresentative, half truth. Sure- Germanic mythology, Scandinavian Scandinavian, Grimm Fairy, Aesop Fables, all have a negative portrayals as many other predators and livestock predators historically have. I've seen the useless 'wolf pack attack scenes' and 'Big Bad Wolf' character in modern day.
But there are the Chechen's nations symbol, Capitoline Wolf that raised the founder of Rome, nearly all of Native Northern American culture (a whole continent), European heraldry, Japanese mythology. And I don't think most people who gotten a wolf tattoo got it for the negative connotations.
I can list many positive modern examples from different media but I'll only list 2: "Okami "(my favorite) and "White Fang" which add human traits in order to criticize human nature.
It just symbolism and anthropomorphism; it's something people have done since they could think abstractly and still do. No competent person who knows anything about literature or biology would apply those anthropomorphic traits in real life.
I don't believe in inherent good and evil. Or absolute morality. I can't be a cross bearer if I don't believe in the cross or God.
What does it really matter? I believe there are markers for how reasonable, sympathetic, grounded, introspective, and aware of reality one is. One, I believe, is how adamantly some believes in something (religion for example but definitely not only that) that is unfalsifiable, not evidently true, denies reality, or completely false. And at an individual or minority level, I doesn't really matter unless you're directly involved. People at high levels are more concerning because of power they have. (Like a certain someone thinking electroshock therapy is a reasonable way to try and convert homosexuals and having the ability to make it an option or a mother certain someone trying to force people to renounce their faith and join the army) Also it matter, because if a majority of people around are unreasonable and unsympathetic, just look at David Kato.
Don't know what you mean by brainwashing and "Evilution".
