Any way you cut it, she got rid of that wife so she go after him .
There was something about the wife that bothered her--To Janeway, they're just holograms, right? Why not just recreat the character in a totally different scenario, different planet, whatever?
Nope, she kept the character and the scenario and erased the wife-- she wanted something the man had, he was attached, she had to get rid of--or work around the wife.
Isn't that the standard method behind cheating?
It would have been interesting if the story had it that the characters couldn't be erased, and Janeway had to deal with here and if she went ahead with it.
