Gold is not quite a neutral entity but it’s how it’s acquired and what it’s used for that determines whether it’s good or bad. Gold can be a beautiful wedding ring or part of a microchip for a cell phone, or a part of a launch system for missiles. As a flexible material it has many uses that depends on the user.
With acquiring gold though the process is not cheap. 
While there are gold veins and gold deposits all around, actually acquiring that gold takes time. The process of extracting the gold from the rocks is also labor intensive and time consuming. This of course is one of the things that drives up the rate of gold but being good or bad solely relies on the method of how it’s acquired.
The problem doesn’t lie in the actual process but the people who do this process. Is the labor fair, is the method destructive, is the nature around these mines preserved or destroyed in the process? These are the questions to ask and their answers define whether gold is good or bad.
