It is unknown territory and almost every human fears or at least distrusts the unknown.
I am aware of the NDE tales too but one thing must be admited about them. Those who experience them were not really dead. Despite what may be claimed in our present state of clinical knowledge they just weren't really dead.
If by fear of death you mean terror I have none. If by fear you mean respect I do. I have seen enough to know how quick it can happen.
