Given the evidence of the evolution of hominids from about 3.something million years ago to the present, we hominids have survived because we cared for one another and cooperated. Our survival depended on it. Along the way there was evil and good but good prevailed thus far or we would not number 7.3 or so billion ... up from less than a million just 65K years ago. Think of it this way, we have grown in population by 5 billion in less than the last 100 years. The number of psychopaths in our population range around 3%(est) of the total population that means about 210,000,000 of the world's population could be medically certified as psychopaths....WOW. That is a large number. They get more than their share of the news. Yet, that leaves almost 7,000,000,000,000 who are not psychopathic...enough to overcome evil. This is just an example. Let me put it this way, when evil overcomes good...we all die. Nah. Won't happen. Good humans have a big head start on the bad ones. The same goes for me....my good far outdistances my bad and that's good. Am working to keep it that way as I stumble along to my end.
