Doomed

People say once you have gone overboard, you cannot really come back to your pure self. That once you have felt the bitter-sweet taste of evil on your innocent taste buds, no sweetened food of good can make you come back. The temptation is too sweet, too appealing and too seductive. No one truly stands a chance against it except a saint perhaps. I don't refer to the easy and common things that people mistakenly refer to as evil. No. I am talking about the true evil. The evil that writhes inside your veins, blackening your blood, and explodes within as a giant volcano of hate fills the body up to the brim. The evil that imprisons your mind just as it seduces your heart as a serpent's kiss, vomiting the poison into the very soul. I talk about that evil where not even a shred of light exists. Just pitch black darkness. It was my fault, no, my weakness that I believed it to be otherwise. I had to learn the lesson hard way but I learnt it. Now that I know the truth, I stand on the crossroads of good and evil, whether to embrace the light or let the darkness hug my broken self. The choice is mine alone, just as the consequences will be solely mine.
I cannot decide it, maybe you can help me. But of course you have to know the background first so hold on to your wits, this isn't going to be an innocent ride.
