I have completely changed my mind about the game.
There are things in it that I didn't see before and I have gradually come to love this game.
There is a LOT more to this game than just the lesson about vengeance, but I personally get more out of this particular meaning. Vengeance and justice are the same thing. I've heard so many people claim that 'vengeance is bad' is a lesson they already know, but seeing so many people in real life rant about how someone 'deserves it' when something bad happens to them, I really don't think the world has woke up yet.
Just read comments under true crime videos for example and you'll see what I mean. People wishing hateful things on others despite it doing nothing but spreading more pain. 'Deserve' is a terrible word the more I think about it, and this game really is beyond its time when it shows this lesson and most people still don't get it.
I am so happy to be one of the very few people who see past the madness and love this game.
