(The Twilight Zone) Henry Bemis, now just a part of a smashed landscape, just a piece of the rubble, just a fragment of what man has deeded to himself.
If to deed means "convey or transfer (property or rights) by legal deed," than I'm not sure that man can deed total annihilation to himself. You cannot leave something to someone knowing that your recipient won't exist.
Is there a possibility that to deed also means to do? "What man has done to himself" makes perfect sense.
