 From the point of view of _this_ particular continuation, namely, me, I
will choose injury over death.

Any attempt to claim that injury means "quality of life has been
worsened" as compared to death is...well, I won't say "silly," as
that's not a good debating term.

Let's turn to simple causal decision theory. A man is approaching me
with a large knife. I have two choices:

* Choice 1: Attempt to defend myself, probably causing me some amount
of injury but possibly saving my life.

* Choice 2: Allow myself to be killed.

I get the idea from your paragraph above that you think Choice 1 is
less desirable, as "The effect from the point of view of the
continuations of the victim is that their quality of life has been
worsened."

Am I misunderstanding your point of view about what I should do?

My approach is to optimize for the actual life (reality, branch, world)
I am actually experiencing. Arguments that it would be better for "me"
to allow myself to be killed, or euthanized, so as to make some average
of realities forever disconnected from mine (Everett, De Witt, etc.,
not contradicted by anyone here, at least not recently) is not
convincing to me.

If you believe in this strong form of quantum suicide, then of course
the path to "quantum eugenics" is clear: immediately kill children who
get less than perfect scores on exams, immediately kill anyone who is
outside the societal norms for beauty and charm, and so on. This will
mean, so the theory goes, that in some realities there are mostly
smart, healthy, beautiful, wise people.

And this is what a person facing attack and death will also choose to
do, to optimize his own survival and his own quality of life. Suicide
can be a choice in extreme cases, I think many in society would agree.
But it has nothing to do with branches of Possibilia forever
disconnected from Actuality.
