Well, well, well.... I totally missed that one!

If murder is the order, than I give it to Gertrude, ever the opportunist. If Claudius is calling her death redundant, then obviously, she was of no threat to him.

Laertes loved her (or "loved" her - you know, the question of incest that hung over the family - like father, like son - she would still be useful in many ways to him(?) ).

Then, really, the only reason for Ophelia's murder would be that she would eventually be a threat to Gertrude. Women had to fight for their existence too.

Hmmmm.... Just thinkin'
