HOW TO CREATE A CIRCUMSTANTIALLY EVIL VILLAIN
The circumstantial villain (the person who is against the main only because of the situation).
The evil villain (the 1-D evil incarnate).
These are the two types of villains that we are going to mix today.
Circumstantial + Evil = CircumEvil.
This is the type of villain who is best described as vicious and evil, vile even. The reader will despise this character, and the other characters will buckle under his power. He kills for a living, and he has no remorse for beheading innocent victims in his plight.
