The absurdity called moral and evil: An idea

I find this whole idea of good and evil pretty amusing. This is the vaguest classification ever known to mankind. There is nothing called good or evil in this world. Everything is purely contextual. What may be good for some might be evil for others. What might be evil for some might be good for others. So what is the benchmark? Evil is defined as anything which is morally objectionable. Whose morals? Whose objection? Whose rules are to be followed? Who made the rules that set apart good and evil? Who made these arbitrary tenet that certain things are right and certain things are wrong. But nobody has a clue on what basis good and evil has been defined. Some say good has been defined as something favourable to the sustenance of the society. In other words a man’s self interest has to be traded off for the interests of the society. A man instead of living for himself is forced to live for the so-called benefits of the society. Everything that we see around the world today is because of man’s inherent nature of self-interest. Till somebody is not being destructive, everything should be acceptable. But still we are taught from childhood that selflessness is a virtue. Why? Selflessness amounts to the cruellest form of depravity. My strong view is that the laws that define good and moral are made by weak people who are insecure that they will be overpowered by the virtues of self-interest of mightier people. There is nothing called inherent goodness of man. Everything is programmed into the mind by the incessant teachings right from the day he/she is born. Everybody is just playing a role of a so called ‘good human’ even when his insides are churning. There is nothing called evil. It’s anything that does not conform to the random idea of moral. It’s a myth that society needs a code. As the joker says in movie ‘The Dark Knight’-When the chips are down, these civilized people will eat each other. If you really need a definition for morality,then there can be only one rule. There is no morality above man’s self interest.
