Plucking nose hair won't kill you and is not really dangerous.
However plucking your nose hair too often could lead to infection of your nose so I would avoid plucking nose hair.
Plucking nose hair can be painful as well and it's best to just use a nose hair trimmer to trim the nose hair instead of just plucking it.
But if you pluck the nose hair you're not gonna die as a result of plucking nose hair but you'll feel some pain and possibly get an infection.
I've always just used a nose hair trimmer to keep my nose hairs trimmed which is less painful than plucking it and I won't risk infections.
