but I think the message that old Janeway was trying to convey (not very well) was that from here on out (Endgame and forward), the cons would outweigh the pros in Voyager's journey. Sure, they lost some crewmen before, but they did a lot of "good" in the DQ. The remainder of the journey was full of death, doom and gloom, and few positive results.
I can just imagine Janeway going to speak with Carey's widow using that argument.
Janeway: I'm so sorry for your loss. It's so ironic that after ignoring him for six years I finally decided to include him in a mission, and he ended up dying.
Widow: You said a future you came back to help you get home. Why didn't she come back a few weeks earlier to save my husband?
Janeway: Well my future self said that only dark things would happen
after the point where she decided to help us.
Widow: Why didn't she go back to the very start of your mission and help you get home right away?
Janeway: Well there is this Borg woman we rescued from the collective...
Widow: So this Borg woman is more important to you than my husband?
Janeway: Weeeeell...
Widow: Does this Borg woman have a husband or kids?
Janeway: Nope, all her immediate family are dead or assimilated.
Widow: So you thought it was more important to rescue this woman with no family than it was for my kids to see their father again?! Do you have any idea what you put us through? We thought he was dead for years! Do you have any idea what it is like having to tell your children that their father isn't coming home? And then he shows up alive. It was the happiest I've ever seen my kids! They missed their father so much! And now you tell me that he's dead because of an arbitrary decision that you made?!!
Janeway: To be fair, you haven't seen this Borg chick in a cat-suit!
Widow: You are a horrible person!!
Janeway:And yet I've been promoted to Admiral.
"Endgame" is another word for checkmate, which makes perfect sense considering the main part was the showdown between Janeway & the Borg Queen.
Well to me it sounds like a hackney one-word title. I don't like the use of one-word titles, I think it's a symptom of lack of imagination. Some episodes deserve cool-sounding one word titles, Scorpion for example, but I noticed quite a lot during Voyager's final seasons. Enterprise too.
Janeway did all she did to get them home but what did she come home too? She came home to an empty house, Janeway lost her future in the Delta Quaderant. She had to go back, she had to bring her family back with her.
Read my play above. If that was Janeway's motivation then she was completely self-centred.
