When they split B'Elanna, the Human half that wasn' killed was unsustainable.
She would have died without reintegration with remnants from the Klingon corpse that also used to be her.
How tidy.
Meanwhile in Deadlock they all became unresovlable transporter accidents who have to accept that are all %50 the people they used to be. Half men and half women.
Meanhile how many people did Tuvok murder in repression?
3?
4?
Sure Janeway can't have known about that, but the brainwashing was inside Tuvok and just waiting for a trigger so that he can murder death kill the Maquis crew all and sundry.
Tuvok living means that every Maquis on the ship must die, and depending on how competant he is, they will all die.
I don't think Tuvok killed anyone in Repression.
