Why am I so angry?

I just pulled my shit together after an angry fit. It came out of nowhere. Firstly, it would be relevant to state that last year I experienced a deception with a person I held close to my heart. The details aren't important. Suffice it to say it cannot be described what I would have done for that person back then, and what I would do to them now. I'm not as affected by the event now, but I still have a lot of hatred left. Pure, unrelenting, biased, hatred. Hatred I never imagined it would be possible for me to muster. And above all, unresolved hatred.

I still have revenge fantasies with that person. Sometimes I imagine them being struck by misfortune so hard, and me watching metaphorically above them, gloating shamelessly. Or they bring themselves up to request my help on something, after which I stay them up with no explanation given; I dupe them, just as how they duped me. Or I kidnap them and hold them in a dungeon, torturing and keeping them on the razor sharp edge between life and death, awakened just enough to feel the constant agony I pour upon them in revenge. I have no room for pity, or compassion, or empathy. I have no room for ethics. I know I'd be evil given the chance, and I don't try to justify it. Even though they would not deserve such ire, I no longer care. I am a beast, albeit chained, but once the chains break, the word "mercy" shall be wiped from the dictionary. At least as long as either of us are alive.

I am angry. There was also a prick on the Internet, nothing new. A troll, though mild, still no less annoying, especially considering my state. Fuck you, Internet. Fuck you, humanity. And fuck you, life!
