There are lots of prevailing notions that are subconsciously embedded in our brains, that we unknowingly make associations with something we learn for the first time. Therefore, while learning anything new we have to do two things. First, we have to get rid of put aside all our prejudiced notions and opinions we have on certain subjects of life from our head/brain. Second, after having understood the new concept, we have to compromise our existing knowledge with the new concept and make a stand within ourselves.

Does absolute evil exist?

Now, let's look at the two key words "absolute" and "evil" separately first and then decide.

The word, "absolute" can mean two things.

i) Something which is not dependent on anything else. It is self-existent.
ii) Something that is perfect and whole.

"Evil" is something which is very difficult to define. It is very subjective. Something which seems evil to one person, may not be so for another person. If you say evil is something which does harm to you, then obviously it is a subjective definition. If you say evil is something that goes against good, then this definition is also not clear.

So now we can answer. Does absolute evil really exist? Objectively speaking, it cannot exist! Absolute evil is like an oxymoron in itself. If absolute evil does exist, then are you telling me that this entire world is full of evil? It cannot be. So absolute evil does not exist.

Let's look at this from the theological standpoint. Abrahamic religions believe in both God and Satan. Meaning that they are saying there is both absolute evil and absolute good. Now, let's ponder over the following points:

1) How can there be two absolutes?
2) If there is both evil and good (Satan and God), then they cannot be absolutes. SO there must be another absolute entity that must have created both the evil and the good. Who/What is it?
3) If there is absolute evil and if you say that this evil was born out the good God, then you are compelled to think, "how can evil arise out of good?" Doesn't it mean then that the God is not all-merciful? Why would God want to unleash the evil upon the world?
4) If the good God is able and willing, then there should be no evil in this world, only ignorance of the good.
5) If God is willing to prevent evil but not able to, then he is not omnipotent.
6) If God is able to prevent evil but not willing, then he is malevolent.
7) If God is neither willing nor able, then why call him God at all?

So in conclusion, there is no such thing as absolute evil. There is also no such thing as absolute good, while thinking logically under the same premises. Doesn't this automatically point out to the non-duality of this universe?
