You're encroaching on ideas of self and self-actualization now, all very different from attributing meaning to aspects that result in or are related to life. Neither wanting to protect yourself or others is against Nilhism per se, mainly I think because acknowledging the pointlessness of something does not immediately or unequivocally make something else reasonable or justifiable. For example, if I say I don't eat fish it doesn't necessarily mean that I am okay with you punching me in the face etc...though, it would make a nice Monty Python sketch.

How can something be moral or not in the face of meaninglessness. Just to use a ridiculous example, if I poop in the woods, that poop has no meaning to me so you can light it on fire or eat for all I care. However, if I work hard and buy a car, that car has tons of meaning to me so I do care if you light it on fire, or eat it.
