Tarrant.
Gerald Tarrant is also the name of one of the protagonists in The Coldfire Trilogy by C.S. Friedman. Tarrant is a very memorable character - handsome, intelligent, mysterious, the best magic user in all history, etc. but he feeds on fear. His backstory has him sacrificing his innocent wife to the Satan-equivalent in exchange for immortality as a vampire-like being.
When I was a teenager I totally thought Tarrant was hot.
Some people probably see themselves in Tarrant, murderous hobbies included.
