The time that he kidnapped Flash Thompson (Luring him in under false pretenses.) and got him drunk when he was overcoming his alcoholism. He then had him put behind the wheel of an Osborn truck, framed him for driving drunk and put him into a coma. Man, THAT was just cold and worse than Gwen's Death! Also, him abducting his OWN GRANDSON and turning him into a Carnage ranks up there as well! If it was actually established that Norman actually DID kill Peter and MJ's unborn baby, that would rank as number two (I still say that getting Flash drunk was the worst!). What do you guys think? I actually like Norman more as an irredeemable flat-out-evil character.
