Humans are Vindictive... So, in essence, you are running about average.
Don't worry. To err is human. To err again is Foolish, but is also human. To err a third time is stupidity, but is also human.
he fact you are vindictive is not a problem, but it's the fact you let it overpower you, and you almost go and make a terrible mistake, is the error. We all make mistakes, some big and some small. But the true power of humanity is the idea that we can learn from these mistakes, and then do better the next time!
I have much distaste for the saying:Those who don't learn from their past are doomed to repeat it.
If all of humanity would LEARN from their mistakes, then we'd have no problem... But the fact is that the majority of humanity fails to recognize their mistakes and therefore is doomed to make the same mistakes. We can just know when to get out of the way when the world starts sucking, and then ride the wheel instead of being caught under it...
The moral of this lesson? Don't be an idiot, loathing your past! Learn from it. Don't be sad because you are human, but smile that you know that you can control yourself next time, and that he's going to get his... That's why the Law of Three is there in the first place. The Universe will balance itself out.
