This is far too open ended of a thing to describe. The best I can recon is that the concept of Evil is a the opposite side of the Hegelian variable to be measured against Good. Given this, it may be easier to define Good first. Good (adjective) = Having the qualities that are desirable or distinguishing in a particular thing. So, evil is that which impedes having the qualities that are desirable or distinguishing in a particular thing. I'll go one step further, but you'll have to confirm if it's what you mean. Define the particular thing as virtue. Evil: that which impedes virtue. Note that I mean virtue as something that is what makes us tune into reality and nature. While the learned elders subvert with gold, and say that one who rules with morality (i.e. virtue) is a bad ruler. Note that gold has no value once all abstractions of what gold provides, i.e. when we're aware or in a state of pure survival. Thoughts?
