Red Skull killed a few people, I'm sure they were parents. lol. Thats pretty evil. He also wanted to destroy major cities and kill millions of people. If thats not evil, then idk what is. He didnt need to do anything sick. Wasnt that kinda film.
But in the comics, what defines the Red Skull is a wiliness to do twisted and sick things, that's his character is about.
Who did he kill that were supposed to care about, that random henchman? Every villain usually manages to kill a few people, in the movies, Magento and Ra's Al Ghul kill a few people, that doesn't make them pure evil. The thing that makes an act truly evil in fiction is to have an act with a real impact, where the vileness has an impact on the characters and the viewers. Shaw killing Magneto's mom has far more of an impact then Red Skull's rather generic acts of villainy.
He didn't succeed in killing millions of people or destroying major cities, trying and failing to do that isn't nearly as evil as succeeding in doing something evil. Failing to do it, just makes for a rather generic villain. Saying Red Skull is truly evil because he tried to do something truly evil, but failed to do so doesn't work, almost every villain out there has tried to do something evil and failed to do so. Heck 80s cartoon villains have tried to enact devastating plans to take over the world and have failed, I don't think they are truly evil based solely on effort.
While I agree the Red Skull never had one big defining moment that really portrayed his villainy, you can't say he wasn't absolutely evil. He had little bits here and there that demonstrated his disregard for human life and his ambition to rule the world. He killed his own officers and other nazis without hesitation and didn't let anyone or anything get in his way.
He was about as evil as a goofy James Bond villain, who wants to rule the world and offs his own minions, that is not absolutely evil, that's just standard villainy. Absolutely evil are acts that go beyond that. Red Skull in the comics went far beyond that, he wasn't just interested in just power, he had a cruel and sadistic side and would commit horrible acts that wouldn't necessarily bring him power, because they amused him.
My thoughts exactly, he was sufficiently evil.
Except the Red Skull is supposed to pure evil, not sufficiently evil. Take that away and the core of the character is gone.
