quick critique of thesis?

For a modern reader, Hester's punishment for adultery, being forced to wear a scarlet letter as a mark of shame upon her breast for life, may seem harsh and unusual. But the punishment is extraordinarily lenient in comparison to the Biblical and legal punishments that were available at the time. Famously, the Bible used by the Puritans states, "Thou shalt not commit adultery" (Exodus 20:14). Furthermore, Leviticus 20:10 states, "If a man commits adultery with the wife of his neighbor, both the adulterer and the adulteress shall be put to death." Jesus made adultery encompass adulteries of the heart in addition to the adulterous acts themselves: "You have heard that it was said, 'Do not commit adultery.' But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart” (Matthew 5:27-28).
