Well-argued, and to me it leads to one of the nastiest questions in morality/ethics: do my values make me more likely to die, and if so, should I sacrifice certain values for pure survival?

In case we're still thinking of "minds-in-general", the world of humans is currently a nasty place where "I did what I had to, to survive!" is currently a very popular explanation for all kinds of nasty but difficult-to-eliminate (broadly speaking: globally undesirable but difficult to avoid in certain contexts) behaviors.

You could go so far as to note that this is how wars keep happening, and also that ditching all other values in favor of survival very quickly turns you into what we colloquially call a fascist monster, or at the very least a person your original self would despise.
