Question

Wht does the quote in macbeth when he wife dies .." she should have died hereafter.....signifying nothing mean

Answer 1

This what I found after researching, but I think (2) is the most accurate.

This line has caused much debate. Four possible meanings are: (1) she should have died after the battle when there would be time to mourn properly; (2) she should have waited for me, seeing that my death is so near; (3) she would have died at sometime, either now or later; (4) she should have died after the battle for now, with her gone, I know I shall not win.
