"Man is the greatest enemy of man. Oppression, injustice, contempt, contumely. violence, sedition, war, calumny, treachery, fraud; by these they manually torment each other; and they would soon dissolve that society which they had formed, were it not for the dread of still greater ills, which must attend their seperation." (Part 10).
Man is the greatest enemy of man. Our own injustices are created by us and upheld by us. It doesn't make sense that there exist an al-mighty being who creates evil.
If God exists, why is the world so unjust.
