The last I saw of Count Dracula was his kissing his hand to me, with a red light of triumph in his eyes, and with a smile that Judas in hell might be proud of.

– Bram Stoker

Dracula, Chapter 4. Jonathan fears Dracula at this stage, he knows that he is evil with red eyes and a satanic smile. He makes a comparison between the Count and Judas, the disciple who betrayed Jesus.
