There are three kinds of people – really the same person in three different stages – mainly the childhood stage when you don’t think bad exists (hopefully;) then the realistic stage, when you begin to fear callous cruelty; but ultimately, we will all get to the true stage, the stage of all the great Jewish saints and prophets, and in fact anyone using their intellect (instead of reacting based on emotional desires, namely, love or fear) there is a God and the goal of life is growth, and all that occurs continually leads us towards greater growth!
