you set up the discussion asking is 'A' more important or is 'B' more important.
from the start you want put things into a dialectic, this or that.
but the world is not flat and black and white. how do you measure importance? how do you measure forward/backward?
is there a need to decide? why can't 'A' and 'B' be just as important, or as unimportant? is human life that clinical and measurable? if you want to quantify everything, why don't you try quantify the value of your existence?
