I have plenty of hate, rage, resentment, though I hope these feelings fall within the normal range.
These bad feelings have often led me to try a revenge story. From an aunt who exploited my mother's death to a coworker who spews nothing but frigid dislike my way, inspiration from real life made revenge stories appealing.
Much to my surprise, I can't do it.
The process of figuring out why the protagonist is a target of evil deeds requiring revenge, and the the process of motivating the antagonist leads me to this annoying place of understanding, and all the air goes out of the revenge story. Perhaps if the wrongs I suffered weren't all first world problems instead of problems that kill, maim, or derange my loved ones, it'd be different.
The world doesn't really need any more hate, anyway. Here's to love! Conflict, sure, but revenge, not from me.
