That's because Slade is the best villain, he brought a whole new terrifying atmosphere to the show while showcasing his strategic brilliance, but also had a very complex story arc where we witnessed his fall from a hero to a villain. He's also an absolute badass when it comes to fighting, back before Arrow fights became so wussy. When Slade does something bad, you don't want him to die for the horrible act, you want him to stick around to see what he does next.
