if Vi is downward it will hit going faster
think what happens if Vi ----> infinity downward (upward is + )
gravity becomes unimportant compared to Vi t

You are correct. If the initial velocity (Vi) is infinitely downward, the effect of gravity becomes unimportant when compared to the enormous speed of the egg. In that case, the egg would hit the ground with a very high velocity.
