I'm not sure I've successfully communicated my feeling about this. It's less like a total dread of death and more like a total dread of losing life, if that makes any sense.
Do you have any close loved ones---a younger brother, a daughter, a close friend? Anyone for whom you might consider sacrificing yourself; anyone who you believe to be a shining light unto the world. Say that person is eaten by cancer. Once they are dead, they feel no pain; this is clear to me, and is not central in my judgement.
What is central is the lost blossoming of a mind. A rich internal experience, a reflective world with joy, dreams, and curiosity, is not a thing that should be destroyed. A mind that wishes to continue seeing the world and its people, and other minds wishing that mind to continue shining its light, annihilated---don't look away from the pain! If you look away from the pain, you lose your already slim opportunity to fight back.
