The concept of a "hero" in storytelling tends to go hand-in-hand with that of a protagonist, the central character. Usually, this is someone the audience is expected to root for, or at least sympathize with. Usually, the audience wants to see the hero come out on top. The concept of a "villain", on the other hand, with a handful of exceptions, is usually interchangeable with that of an antagonist. That is, their job is to oppose the hero by creating obstacles that need to be overcome. Many video games thrive on the clash between heroes and villains. Having solid chemistry between opposing characters can drive a compelling story, but sometimes, things can change in unexpected ways. The fact is, even the most well-intentioned heroes can't achieve their goals without making a few enemies, and the price of heroism can be high. Sometimes dangerously so.
