When a team uses a review, they are asking the third umpire to overturn the decision. The decision can only be overturned if, using the available technology, the third umpire is 100% certain that the original decision was wrong.
Hawkeye has a small margain of error. If you're looking for an lbw decision to be overturned, if Hawkeye shows the ball just clipping the stumps, that's not 100% conclusive proof that a not out decision was incorrect. You cannot look at that and say "the ball would probably have hit the stumps, overturn it." If Hawkeye can be developed so that the predictive element is 100% accurate, then yes, there would be no marginal decisions.
