Even though Sandman isn’t on here, I’ll quote a great line of his “I’m not a bad person, just had bad luck”

Mysterio doesn’t get much background story, but he clearly comes across as the biggest dick whose mind doesn’t appear to be altered by some science experiment.

Norman was desperate to help the company he himself built along with the US military, and if not for the Goblin’s influence he really did care about Peter like a son.

Ock wanted to create renewable energy and had his inhibitor chip destroyed which gave the tentacles control over him.

Connors just wanted his arm back, and Electro starts off as just a normal electrician down on his luck who gets in an accident.

Eddie Brock is a slimy journalist who lies and cheats at his job, and then prays that God kill Peter Parker after he gets exposed by him. So the only two “evil” people on this list are really Venom and Mysterio.
