The reason Venom is so aggressive, hateful, and violent is because the first person Venom ever bonded with was Wade Wilson very briefly. This caused Venom to imprint on Wade and mimic his personality. (except for the comedy, plothole ig) This caused Venom to influence Peter into being a more violent person, not the other way around. The only reason Eddie got Venom to be a hero (kinda) is because of how stubborn and willful he is. Interesting thesis though it makes sense
