Well, not in real life, of course.
But in fiction, a villain is a necessary evil.
The hero of a book needs to have someone to provide a challenge, an obstacle or a conflict or else the reader gets bored.
When the villain is particularly nefarious, the stakes are raised.
Think of The Joker, Voldemort, Cersei, Darth Vader, or Nurse Ratched.
These guys just keep on coming, no matter what level of good or compassion is offered.
My villains (and yes, I have to create them to vex the protagonist) tend to be intelligent, entitled, and self-involved. In my previous world of work there were enough of them to be able to choose traits from one and habits of another to create someone you love to hate.
