Why is Odysseus dishonest?

Odysseus repeatedly formulates and executes acts of pretense. In the Iliad, he sneaks into the Troy disguised as a beggar and thought up the idea of the Trojan horse. In The Odyssey, he repeatedly thinks up schemes in order to escape near death experiences, such as covering himself and his men in sheepskin to escape the Cyclops. Odysseus' entire worldview, as evident by his actions, is one of pretense is necessary at times in order to succeed.
