The best minds will tell you that when a man has begotten a child he is morally bound to tenderly care for it, protect it from hurt, shield it from disease, clothe it, feed it, bear with its waywardness, lay no hand upon it save in kindness and for its own good, and never in any case inflict upon it a wanton cruelty. God's treatment of his earthly children, every day and every night, is the exact opposite of all that, yet those best minds warmly justify these crimes, condone them, excuse them, and indignantly refuse to regard them as crimes at all, when he commits them.
