Who killed Cock Robin?

Apparently, the nursery rhyme I knew as Who killed Cock Robin? is just the last part of a much longer poem called The Death of Cock Robin. Reading that animal fable of love, marriage and violent death, I actually understood how and why the Robin was shot. That sparrow (with his bow and arrow) was apparently not the villain I had thought him to be.
And poor Jenny Wren!
For some reason, the thing reminds me a bit of the Death of Baldur.
(I was reminded of the Cock Robin poem by listening to Bauhaus’ Who Killed Mister Moonlight? I feel silly explaining this.)
