Ock killed capt. Stacy by accident, his tenticles got messed up and knocked down a chimney, he didn't do it intentionally. Betty Brants brother was killed by a gunman...I thought he got shot. He neally wed Aunt May but spidey stopped it, Ock never really did anything to hurt May. All of GG's actions were intentional where as Ocks weren't always intentional. I don't view Ock as being a killer...Ultimate Ock may be a little different.
