Deathism
From ImmInstWiki
Deathism is the family of philosophies, psychologies, attitudes, positions, opinions, and viewpoints that death (the cessation of physical living) is both desireable and good, and that all attempts to "unnaturally" change, alter, delay, or prevent it is undesireable and bad. It is strongly or tenatively held not only by many Goths, Satanists, and Dark Pagans, but also by nearly all Christians, Muslims, New Agers, atheists, agnostics, Wiccans, indeed nearly everybody.
The main people who do not hold deathist views (and of course the ones who have coined the term) are the immortalists, particularly the biological immortalists and transhumanists, but also perhaps the Setian (ToS) Satanists, some Technopagans, and others. These people wish to work against death (nothingness; nonexistence; nonsurvival) and all that it stands for, such as "merging with the whole" (Nature/Universe/God), surrendering to the Other (God, etc.), and other ways of losing your conscious identity, autonomy, and sovereignty. Antideathism is definitely a Left-Hand Path philosophy, while deathism is usually very Right-Hand Path (even most modern neo-paganism that promotes altruism and nature-worship over egoism, immortalism, and the Self).
Deathism traditional: for such a person death of old age is desirable. Rebelious deathism: a desire to take everything of life and to die young.
