Balance the equation?

So, this non-dual vs dual nature of universe has been on my mind lately. The more I look, the more I find good and bad together. Seems like there is a design for some of us to do bad, so that others have a chance to do good. Those who are doing "bad", firmly believe that what they are doing is right, which means from their perspective, they are doing good. It is very clear to me know that there is no definition of good or bad. It is a matter of perception, depends on where you are standing and what your circumstances are. And yes, it applies to every thing.

Well, on top of this, I ended up watching the last two movies in Matrix trilogy. It was not a planned activity but happened because I am on vacation and can afford to watch TV late into the night. I think the person who wrote matrix is enlightened. I don't know how they know so much but boy, they do have some facts straight at least. So, the one that resonated most with me was the unbalanced vs balanced equation. The things that were bothering me for some time are --

1. Why is there good and bad?
2. People who do bad are convinced that what they are doing is not bad, so in their mind, they are doing right.
3. There is no self, so there is no entity making up its mind about good or bad.

The statement in matrix was that there are some of us unbalancing equation and others are balancing. If this was not happening, probably no one would have anything to do! And my finding is that every one is balancing and unbalancing the equation. We all are a mix of good and evil, some less, some more.

Cannot stop thinking about it..suchness of Universe..good and bad

So..the Universe is such..there is ignorance, the root cause of all suffering. Ignorance about not knowing the real nature of things as impermanent, devoid of self sustainig and self creating cause. This is why we cling, we get greedy and we hurt others mostly because of our greed. BUT this is no one's fault..just like leaves are green and stone is hard, this is the "suchness" of human nature. We are born in this manner. When we hurt others, it is rarely because we intentionally want to hurt, but because we are bound by our nature based on greed and need of security. Rape, theft, war crimes, terror - for all these, people who are doing them absolutely believe that they are doing the right thing. In their minds, this is the best action they can or should take. People hurt others, create bad karma unintentionally and then suffer in return. The thing that is baffling me is that this is how the system is designed..no one made it like this..this is how it is..BUT WHY?????????
