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.
