We understand that in Christina Rosetti's poem, prostitutes are not deviant. They led lives of suffering. it is not a life they chose. this is something that Rosetti depicts in the Goblin Market when the Goblins, representing men, force her to do their bidding. However, Lizzie walks away with her dignity intact. This means that the gross acts of men on helpless women doing what they need to do to survive, does not devalue them from a virginal state when in a devirginalized state. Lizzie is only trying to save Laura's life from death in getting the Goblin Men to give her fruit. However, things get more complicated where Laura sucks the juices from Lizzie's mouth and Lizzie wants it.
But far more than that, her sacrifice is comparing that of a prostitute to the Christ figure.
There is no doubt Rossetti intended to make Lizzie the prostitute into the Chirst Figure; however, her message becomes more obscured when Lizzie wants Laura to suck the juices from her mouth.
innocence>temptation>not the fault of everyone who gives off the appearance they intended to be tempted?
