there's a better world out there, believe me. you are alienated by living in such a pool of sharks. you won't believe how relieving it is to live in a world where you can trust people
Have you noticed that the Odyssey is one long celebration of doing exactly that?
I'm not sure Greek myths are great sources of ethical behaviour given, you know, all the rape, incest, bestiality, cannibalism and more.
Quite a lot of Greek myths, when not stripped down to the "simplified for story-telling to kids" versions, are straight-up case studies / moral lessons to adults.
I'd never look at the Odyssey and mistake it as something to emulate. That people do is kind of surprising.
If you have to go back to the time of the writing of the Odyssey to justify for your behavior, you're probably doing something wrong.
if you become successful at the venture, then was it lying in the first place?
It obviously was still lying, even if you are successful. How is there any question? You either lie and are unsuccessful, lie and are successful, or lie in a legally material way and are sued or fined, and are either successful or unsuccessful. All outcomes still started with a lie.
