Yup sure can. Would have been zero skin off my back too. Sadly I can imagine the ratings would have suffered somewhat without her.
I don't think the ratings with Voyager were all that impressive anyway, especially once the "ogling" factor over 7 of 9 died down a little.
Let's face it, TNG was successful in part because it was a syndicated show (how many shows are syndicated during their run anymore ). That meant the networks couldn't tell Roddenberry or other Executive Producers how to run their show. If Roddenberry had lived up to Enterprise, I think he'd have never agreed to part of a network again, especially after his experience with NBC. And becoming part of a network is what I think helped kill Voyager and Enterprise (which, I'll admit, isn't the only reason).
It also turned the poor DS9 series into the red-headed step child of the Star Trek universe.
Killing characters (especially popular ones, and love her or hate her, 7of9 was popular) is often just cheap and manipulative. Set 'em up and knock 'em down.
Rarely, it is done well enough to be artistic and meaningful. Usually it's about some writer who wants to make his bones by shocking the audience. Some people call this fearless. I don't agree. It's the kid at the beach kicking over his sandcastle before he goes home so noone else can play with it. It's selfish. It's a great big "Look at me! Look how awesome and powerful I am! I can make you love, I can make you cry! Dance puppets!". It's the mentality of the bully and the demogogue.
That said, it would have happened in the last episode of the series and there was no real feature film future for that franchise anyways. It would have been a little less 'deus ex machina' than future-Janeway muddying the timeline to assuage her guilt (and where are the g-d Time Cops when stuff like this happens?), but not necessarily better or worse.
Ture, but when you do kill off the main guys, you might mess up any come backs you have planned later. Like in film form. But it did work with Spock, he was killed off in Khan, and came back at the end of Trek 3.
In Sevens case, I think it would be a shame to have her go out like that, it would leave a bad taste in the fans mouth. l
Killing 7 would have been interesting, but I don't think would have made the series finale any more poignant, or "Human Error" (great as it was). I think a more interesting what if is how 7 will intergrate (or not) into Federation society as a whole.
No one really dies in Star Trek anyway. Even ol' Tasha Yar comes back every now and then.
