An explanation...hmm. First off, while there is a 'purpose' to this, I don't want to claim any attitudes towards the content of this poem. It's up to the reader to decide what I think about the subject matter. As for the poem:
The tree is Jesus. The caterpillar is Judas. The whole thing is a fictional dialogue between Jesus and Judas before the betrayal. According to the new gospel, Judas had visions of betraying Jesus and told him so, to which Jesus answered that he would do so because he loved Jesus. This poem is about the fate of both of them, and the last line of each stanza should (with a little thought) tell you the purpose of the piece. Whether I am pro or contra Judas in the poem is for you to decide.
Does that help?
