Perhaps you are confusing good with righteousness... or something similar....
For as far as I can tell... good isnt exactly the opposite of evil... good is a relative thing. No... not exactly, on second thoughts.
The word, "good", as many words, has several meanings. One is the word which is similar to "righteousness" and which represents the cumulative traits of truth, kindness etc, and the other main meaning is the one which everyone else is arguing for. ie, the relative meaning.

Since there have been so many explanations using "logic" lately... try this logic....
You are both arguing two separate points... the word has two separate meanings... no one can deny these meaning exist... Therefore this whole arguement is rendered moot.
Well, kind of... y'see, theres not much in this world thats black and white... I'm sure you will all find a way to reorganise your arguments so they take my point into consideration... but i hope this has at least cleared up this what is good business.
