Whose wife had deceived Odysseus?

yes it is very, very wrong:(

Answer 2: No. He does it for a purpose which help both of them live happier lives. Further, he needs to preserve his life so that the suitors do not try to kill him before he is ready to kill them.

It depends on what deception is being spoken of. If talking about Odysseus' liaisons with Circe and Calypso, then yes, but one cannot refuse a god, and telling Penelope the truth might only create a greater wrong and compound the error.

Answer 3:

No it is not wrong to deceive her because then he can protect his identity from everyone except his son because he needs his son to help kill off the suitors because if he told Penelope then she may accidentally tell someone that he has return then they would both be in trouble.
