If your "basic instinct" was "survival," and if your basic nature was "evil," you would never move instinctively to save a child from falling, a man from drowning, or anyone from anything. And yet, when you act on your basic instincts and display your basic nature, and don't think about what you are doing, this is exactly how you behave, even at your own peril.
Thus, your "basic" instinct cannot be "survival," and your basic nature is clearly not "evil." Your instinct and your nature is to reflect the essence of Who You Are, which is fairness, oneness, and love.
