Perspective
Prelude
There are no such things as heroes and villains.
It's all a matter of perspective, really. To so-called "heroes", their enemies are villains. To so-called "villains", their enemies are also villains. We decide who the heroes and villains are.
There's an expression – "history is written by the victors". And it's true, because that's where we even get the notion of heroes and villains. The people who write history always call themselves the heroes and the people who oppose them are always the villains.
People can't be classified into categories like heroes and villains, good and evil. We're both. It's not possible to be entirely good or entirely evil, because what defines good and evil? People do good things and have bad intentions, and people do bad things but have good intentions.
Therefore, there are no such things as heroes and villains.
