I think it is very myopic. I think that people who such terms as "good" in this context need to learn a greater perspective.
Firstly, we notice and internalize loses more notably than positives. One could see "Good" as simply waking up every morning. In that way, I could say that I have had 13,180 "good" things happen. When we consider scale I would say that over all more "good" than bad tends to happen.
Second, is our perspective. When a job we want goes to someone else, we consider it "Bad." yet someone else considers it "Good". At that point, do we need to consider is the better person? Tally up who has had more "Good" happen in their lives and thus is less deserving?
My cousin was 26 when he died suddenly. He was about to get married and had kid @2 on the way. It was tragic and a loss to many people. In the end it I received his kidney. Was my life worth it? Personally, I don't think so. I have no family depending on me. I do have many friends depending on me, many who say they would not be here if not for me. My cousin was a good guy but his family...let's just say the liklihood his family would have fallen to drugs and jail time was a possibility. Hell, not long after he died some Russian gang members came looking her him ( due to his relation with an ex friend) had they found him alive maybe the entire family would have been in trouble? So, did his early death end up a greater good?
I can't say. No one can. The world only on casualty, not on a 1-1 ratio of good v bad. So, I think it's an absurd concept.
I will say however, that it is much EASIER for 'Evil" to win due to it's very nature; it does not follow rules or morals.
