The villain in a thriller is generally not your run-of-the-mill murderer. He is someone with a goal in mind, and he is driving toward that goal, regardless of the damage he causes along the way. While he may enjoy that destruction, whether human (serial killer, assassin, strong-man dictator) or property (arsonist, bomber, unscrupulous land baron) he could just as easily be someone who reluctantly sees the damage he leaves in his wake as an inevitable cost to the good he thinks he's doing (religious fanatic, environmental extremist, patriot assassin). While she may be evil, to me it is much more fascinating to read about the villain who thinks she is the hero of the story, who is a true believer in a cause she has either lost perspective on or has just gone too far in support of.
Either way, his plans are greater than a single act, usually building to some larger, ultimate goal that our protagonist must prevent. In the book Silence of The Lambs, [SPOILER STARTS] Buffalo Bill is building himself a lady-suit [SPOILER ENDS]. In the film Taken, [SPOILER STARTS] Marko is seeking to keep a steady supply of fresh flesh for his human trafficking operation [SPOILER ENDS]. In my own book, Presence of Malice, [SPOILER STARTS] Gerald Gannery is determined to gaslight his partner for the embezzlement of which he, himself, is guilty in order to free himself up to take a lucrative development deal for cable TV [SPOILER ENDS].
The villain's evil usually comes not just from his own selfishness, but from his willingness, even eagerness, to accede the pain and suffering of others in order to meet his aims. Even if she agonizes over each and every life taken, she takes it anyway because to her, the end will justify whatever means she sees necessary to apply.
In a thriller there is the concept of the ticking clock, which I will explain in more detail in the next and final part to this post, but I wanted to mention here (and will most likely repeat next month) that the ticking clock doesn't necessarily have to be a literal clock. In many cases it is the deadline for the fruition of the villain's plans, whether arbitrarily set by him or by his own need for urgency due to other schedules being enforced upon him (the president's plane departs, a shipment to be hijacked is en route, the laundry truck departs the prison, etc.).
As I mentioned before, my favorite villain is the one who thinks she is ultimately doing good, or better yet the one who is besieged by guilt over her own actions but compelled to do them anyway. But there is also something to be said for the gleefully evil - the serial killer, the psycho musician convinced he is a soldier for Satan, the unhinged skinhead with a hidden lair full of torture victims, etc. Whatever your taste, always remember that to keep the tension, either the villain must not be redeemed, or if she is, it must already be too late to stop the events she has put in motion (or seemingly so, until our hero takes action).
I wanted to spend time on henchmen and other companions of the villain who must be defeated on the way to the villain himself, but that will have to wait for another, longer discussion on villains.
Meanwhile, what are your favorite villains? What bad guys do you love to hate? Let me know in the comments, below.
