Here's my thoughts on revenge fiction and where we can be going with it

our protagonists can be committing so much more revenge than they have been

vengeance, like money, is not the single key to unlocking happiness, but it enables a vast assortment of things which can further improve one's life

when it comes to revenge, your rage is the limit

Yup

In Gundam Valor, I want to be like
Preacher: May I offer you some spiritual guidance? Kill him. Just fucking end that man.

"the first step to your spiritual health is eliminating your stressors"

"Breath deeply and center yourself in the now. Then pick up this knife. Visualize where you're going to put the knife."
