Also, as someone old enough to have read the original "Death of Gwen Stacy" stories when they first came out...

Norman Osborne had no "strength and magnetism." He was not the charismatic businessman that everyone has ret-conned him into being.

If anything, he was more the "crotchety dad," who picked on his kid, sort of like Red from "that 70s show"

In fact, that was one of the reasons that his being the Goblin was a shock. Harry's dad was just sort of this rich, loudmouthed "Archie Bunker" type, not some sort of charismatic uber-mensch.
