So we all know that the Skull takes the cake (He is probably THE most evil villain in the Marvel Universe.), but after him, who would be the worst (As in most evil.) Cap rogue? Zemo is not THAT bad or evil (And is he still a Cap villain?), and he's shown that he can be something of an anti-hero. So has Viper (Madame Hydra.). I recently bought some back issues of the original Thunderbolts series (The Busiek/Bagley run.), and one of them was the first appearance of Jolt. Arnim Zola was the one who was revealed as being responsible for creating Jolt when he EXPERIMENTED on her when she was a teenager! That's kind of low, does that even fit Zola? Evidently he also did it to a few other orphans who she was friends with. That's really evil. It sounds like he's the second. Crossbones? I doubt that even he'd do something like that. Any others? Thanks.
