In Night, what is ironic about the warnings of the electric fence, that Elie mentions?
The warnings of the electric fence surrounding the concentration camp are ironic because the fence is certain death to any prisoners who try to surmount it. However, the fence is ironic because it also represents a means of escape and freedom. Furthermore, Wiesel mentions that it's funny they bothered to put up warning signs about the fence when death was lurking around every corner. It was odd that SS officers bothered to warn prisoners of electrocution when they were killing them off in masses anyway and enjoying every minute of it.
