Why does Venom hate Spider-Man?

Venom hates Spider-Man because Peter Parker stole his chance to be a full-time photographer and he wants revenge. Spider-Man got to where he had enough of the black suit and was at the bell trying to take it off. Then the evil stuff on him came off and fell on Eddie Brock causing him to become Venom. So now Spider-Man keeps on trying to stop Venom from doing his crimes. Venom wants to have Spider-Man killed so that he can wreak havoc on everyone who had ever done him wrong.
