You see movies in which blond people are depicted as evil and now you think blondes are evil ???
Please don't confuse the fictionality of movies with reality. Thanks.
Most movie directors are dark-haired people, usually leftist and often even anti-white racists. So, they depict blond people as "evil". It's nothing more but their propaganda.
The Hollywood trope of "evil" blondes isn't exactly the only anti-blonde trope in movies of that propaganda institute. There are also many other tropes like "dumb blondes", "magical negroes" (look at Wikipedia for it) or "power brunettes" (Lara Croft e.g.)
Movies are nothing but subtle racial propaganda and obviously Hollywood is ruled by people who really resent blond men and women.
It's an open secret that Hollywood is riddled with pedophiles, satanists and some other very dubious people. It makes sense that these psychopaths really hate blondes cause usually blond people are among the most harmless, law-abiding and honest people on earth.
The really villains depict the good people as villains and try to convince the world with that propaganda.
