I have macbook pro retina and two tiny tiny pixels are destroyed (white), what caused for this to happend and if more pixels can be destroyed because of these two ?

A pixel in a lcd has 3 subpixels (red, green, blue) that add colour to the white backlight. If it failed white, it means that the small controller failed for the whole pixel. This can be physical damage (bumps, drops) or a manufacturing defect (one of the very tiny wires was made too thin or a bad connection was made) that took a while to show up.

It is entirely possible to have a bad panel that slowly gains more bad pixels, but this will not be caused by the existing bad pixels. It is most likely a defect, as it is difficult to make something that tiny perfectly (millions of pixels per screen).
