Never Ending Unforgiving

Can you really forgive everyone? Is there really such a thing as an unforgivable sin? I believe so and my former family is the cornerstone of such an example of unnecessary hatred and spite; every last damn one of them. Why is this so? To begin, my siblings never really loved or cared for me with the exception of boosting their social status, doing errands for their own ends, and lastly just because they always wanted a pet retard to do their bidding. All those reasons may not be entirely unforgivable if they showed any regret or remorse for the atrocities they committed against me, however, to this very day they still think they are the picture perfect family they have painted over these many years. So what did I do? Did I have vengeance against them for making me inhuman? Do I intend to destroy their future and turn all those they hold close to them against them? Already too late for that. How can you forgive someone you choose to forget with no chance of absolution? Maybe I am weaker than they are, or maybe I am the better man but I just learned not to care anymore because I am a thing of my own making, of my own free will, I can be anything I need to be since they were the ones who taught me to never hold back with any limit. This is why I cannot forgive them, they took the very soul of who and what I was and turned it into a hideous entity hell-bent on avenging a family that cared so little about everything. When they did all those horrible things to me back then, I did things far worse than all of them combined. I wanted to be worse than they were so that they could have a fucking good reason to hate me rather than hating me for nothing at all. Since then I have witnessed never ending unforgiving, a chain reaction of terrible events unfolding one after the other. I witnessed my sister become like our whore mother, my brother turned out like our drug addled father, and my youngest sibling doesn't even know the difference between standing his ground or collapsing under insurmountable pressure. Fuck, I don't even know myself anymore. This rant only has one meaning in particular. Revenge never ends and if you set out for this be prepared to lose who you really are on the inside; because that is the first thing to die on the battlefield of life.
