Would a person receive a shock/risk death if they completed two ends of a neutral wire?
When you cut the neutral the side connected to the load is no longer neutralised and is connected to live through the load resistance/ impedance. That means that when you grab both wires the mains circuit will be completed through your body. A potential divider will be formed by the load and your body and due to the high resistance of your body most of the voltage drop will be across you rather than the load (except for very low current devices)

Figure 1. Breaking the neutral causes one side of the break to go live. The current is limited by the load (the lamp in this case).
Closing the circuit with your body would, most likely, not end well.
