Well, he could protect villains in fanfiction by ensuring they get a fair trial. Spider - Man, being the morally upright hero he is, might believe that everyone, even villains, deserve justice. So he could protect them from vigilante attacks or mob justice until they can be properly dealt with by the legal system.
A common scenario is when the villains are being hunted by a more powerful and ruthless enemy. Spider - Man would then step in to protect them.
