^But that's what Yminale
said. "I find it Ironic that Dracula is trying to encourage Harker to be a better person knowing
that he'll completely fail and be the exact opposite." I think what Yminale
means is that it might appear to the observer that Dracula was trying to encourage Harker, but the truth was that he was setting him up for a fall all along, hence it runs counter to our expectations.
Still, I think I agree with you that that isn't irony -- it's just a character having a hidden motive. And really, since he is Dracula, it's not really counter to the audience's expectations when he does something harmful to another person. What would be ironic would be if it turned out he'd really meant well all along.
