I’ve been thinking this way about certain personality types for years. There is always that special someone that has to have a nemesis in their life, can’t be a superhero without a villain.
The problem comes when the “villain” is removed, there is a short-period, and I mean, very short period, of what seems like relief but then they must go on the hunt for another villain. It’s like an extreme version of inner reflection by constant comparison.
I think we all look over the fence more often than we should and judge ourselves by what others have or do, but this is just an extreme version, making the feeling of “good” from this much more extreme I guess.
