We always label and categorize things as good or bad but in actuality there is nothing good or bad in itself. Either we can say everything is good or everything is bad, not like certain things are good and the others are bad. As a thing has got multipurpose and multiuse meticulous labeling of the thing as good or bad is of great difficulty.
It is our use, over use, how we use and for what purpose we use make things good or bad. The same thing can be used constructively and destructively so how can we label as it is good or bad so what makes a thing good or bad is, for the what purpose it has been used and what result it has elicited.
For instance; a pen that is used for writing can be used for good as well as bad intentions. When the pen is used for writing down something it is a good use of a pen and at the same time it can be used to poke someone so it is for bad intention. So how can we group pen into the list of good things or bad things then? So for what purpose and what result the use of a particular thing elicits make a thing good or bad. So things are of two dimensional good or bad.
However, social acceptance and generalization have listed out things as good or bad. It is categorized that certain things are for good purpose therefore they are good and others are for bad purpose therefore they are bad. Therefore, our use and the result elicited push things into different categorizes as good and bad. So we the user and for what purpose we use a thing give the rightful place for a thing and in reality no thing is good or bad in itself.
