What IS he trying to say here? I mean…he’s trying to imply that the purposes underneath are in Hamlet’s interests and altruistic. But we know (and Hamlet probably knows too) that his purposes are in no way in Hamlet’s interest. So it’s funny to bring up the underlying motives – given how dark those motives actually are. But I guess this is a standard practice in lies…you try to deflect from the lie by stating the direct opposite of the lie…which has a funny way of pointing at the lie. It is tricky business being a villain.
