Superman is always in control, the mxy dust caused him to lose control and he had seconds to fly to a dead universe to let out a sneeze. no where did it say that the dust will make him sneeze with that much destructive force.
Superman didnt want to let out a uncontrollable sneeze because he knew his level of power. Superman was unaware of any amp by the dust. So there would be no point in looking for a dead universe.
