Point of clarity,
@Rubik outed
@Freddeh as
Norman Osborn, at no point did anyone say he was the Green Goblin.
And much as it burns my bacon to say this because I very much don't trust my worst enemy in even the smallest regard, if I remember correctly, Norman was
Town Aligned in
A Spider-Man Mafia 2. I think he had a motivation to make Spider-Man lose, or like he couldn't win if Spider-Man also won, but his win condition was, I think, the same as the Towns. The Green Goblin in that game was one of his minions, who was
Goblin Aligned, and his win condition was, I think, to kill Spider-Man and help Norman win.
tl;dr—Norman Osborn in the lore was the
original Green Goblin, but is not necessarily the
current Green Goblin or even necessarily Goblin Aligned.
