Fornication and Adultery was clearly frowned at, especially in the New Testament since we really want to bring in the "Jesus" Era. The ten commandments was still smashed by Moses upon seeing the vile behavior of the human beings he left to go get the tablet anyway. And Jesus hanging out with a prostitute in your words was his way of showing us how it isn't our duty to judge anyone.
