I'm of mixed feelings regarding death. For one, it is the BIG thing the novels can do to show, "we're really serious here!" OTOH, with the fact the TV shows are off the air, this is also not only killing the character but killing every potential storyline you're going to be telling with the characters.
Killing Janeway killed all C/J stories, all future tales of her adventures, and so on but it also meant the books had a big thing to say, "this is what we do" along with wiping out the Borg. I'm now half-worried we'll find a cube disconnected from the Queen at the time of Destiny and it'll start rebuilding the Collective like the Daleks.
I guess, for me, is I like change but I like changes to stick.
