User blog comment:Prime ShockWaveTX/Pure Evil Proposal: Mysterio (Marvel Cinematic Universe)/@comment-34055410-20190714044003

While one can say the MCU has a high heinous standard, Mysterio, after all, is just a human who happens to have advanced technology. There was a moment near the end where he expressed some respect towards Spider-Man for being a “good person”, but this was just a ruse as he tried to kill Spider-Man moments later (and ended up posthumously incriminating Spider-Man before revealing his true identity). That, and the fact that that he was more than willing to commit mass murder (even attempting to kill teenagers) is enough to make him stand out. “Yes” for now.
