2. 17th century poetry. Why death? - more on Donne's "At the round earth's imagined corners"

Pretty much a close reading of that poem, and its paradoxes, partly via Donne's paradox V that "All things kill themseluses."  We raised and thought about the question what makes death an appropriate punishment for sin.  What is it that Donne is "mourning for a space"?  I thought this was a pretty good discussion.
