How does Voldemort in fact see Harry Potter as?

Ok, take away the fact that voldemort killed his parents and that Harry is destined to have a 'showdown' with his enemy; How does voldemort see Harry, in other words, what does he think of him, as a wizard? As a person? It's just I remember in the 5th book when they are in the dept of mystries and voldemort refers to Harry as having a 'worthless mind'.
