What would happen if nerves didn't have refractory period? And, what part of his nervous system or neurons are not needed?

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
Refractory period returns the repolarization period to the nerve's resting potential . it's the time taken for recovery of a neuron to generate another impulse being excited by another stimulus . so if nerve doesn't have refractory period they wouldn't be able to return to its resting potential & generate new impulse . moreover the repolarization potential further exceeds its value and cause hyperpolarization , so its badly necessary to restore to resting potential by expelling na+ and taking k+ in . unless it would be impossible to restore the resting potential & be ready to get excited to transmit another impulse via the electrochemical pathway . one more benefit of refractory period is that it causes unidirectional impulse conduction. I didn't get the 2nd part of your question. What are you trying to mean , make it more clear.
