I would say Spike is deluded. To say that he is deliberate as well as deluded is a paradox I am unable to quite wrap my head around. The #1 victim of Spike's seductive powers is himself. I think he is pretty sold on his own hype.Spike, being a romantic type who thrives on attention is often deliberately melodramatic. It's how he thinks a lot of the time, even when he's not with Buffy he thinks that she's obsessed with him and plotting to screw up his life in some way- this is evident from S4 onward.
Spike has these delusions of his importance in other people's lives (at least whilst he's soulless) and so he plays to that- that's pure melodrama.
I don't get it. Is this Angel's simultaneous awareness of these two ideas a constant thing, would you say?The dissonance he experiences from the juxtaposition of how he's perceived and how he wants to be perceived is one of the more amusing things about Angel.
I think people ignore that Angel's drama-ness is often appropriate to the situation. Angel's story is a melodrama. Angel himself is just trying to deal.
