Meaning of 「生きるにしても死ぬにしても」


In the video game Mother 3, there is a group of beings called the Magypsy, who
are rumored to be very old. While talking to humans, one of them says the
following:

> 人間なんて生きるにしても死ぬにしても精々たった100年。

Note: The game's text is in almost all kana; kanji are mine. The original text
is, 「にんげんなんて いきるにしても しぬにしても せいぜい たった１００ねん。」

While my guess is that this means something along the lines of, "A human life,
from beginning to end, lasts at best a hundred years", I'm wondering about the
exact meaning of the 「～にしても」construction. Jisho translates 「にしても」as "even if",
but I can't find a way to phrase this sentence like that - "... even if they
live, even if they die..." doesn't seem to make a lot of sense.

Is this some grammatical form I'm not familiar with, or is it perhaps my
interpretation of the sentence that's the problem?




The sense of both verbs is active rather than passive sense. In that case
"live or die as they might" could be a closer interpretation.

It may refer to the fact that humans barely live longer than a hundred years
despite their best efforts, and nothing that they do lasts more than a century
(thus the "die as they might" part).

As for 「～にしても」, it might make more sense if you interpreted it as "even if one
(actively does an action)", rather than the simplistic "even if". It pertains
to the consideration of the performance of some action, rather than referring
to the action happening.

For considering the passive happening of some action, 「～としても」would be your
ticket. For example, 「雨が降るとしても、天気が晴れるとしても、俺は傘を持っているから問題ない。」 would mean
"Whether it may rain or it may be sunny, I've got my umbrella so there's no
problem."

If we were to substitute 「～にしても」for 「～としても」, it would anthropomorphize the
weather by giving it some sort of "will", as in "Whether the rain chooses to
fall, or the weather decides to be sunny..."




The best English phrase that I could think of that would retain the nuance of
the original is:

> "whether they live or die".

You do not need to translate 「にしても」 twice just because it is used twice in the
original. What is more important is how things sound in the target language.

The first 5 characters 「人間なんて」 already tells us that the speaker looks down on
humans pretty badly. The rest of the sentence only reassures that fact.

> "Humans, whether they live or die, we're only talking in the order of 100
> years at best."
