You are a defeatist, no, it's not the same as a pessimist. You seem to believe that humans are inherently evil, inherently destructive ....<quoted text>
But now in the nuclear age the capitalist era have the "chance" to eradicate the human race and they are on its way to do it!
... well we are not, not anymore than any other species. When educated, the human becomes the strongest force for positive change, the species more capable of advancing, progressing, and improving. That's the reason we are where we are now, that's the reason we have the capability to "destroy the planet," so to speak. Today, this is the most peaceful time in the world as a whole, the fewest wars in all known history, the lowest crimes rates in countries that have historically had high ones, like the US for example. We are doing what we, as a species, do best, we are learning.
