Dwayne Burcell

In the Masters of Horror segment/short film Pro-Life (alternatively known as John Carpenter's Pro-Life), a young woman named Angelique Burcell is accosted and raped by a demon. She later goes to an abortion clinic to remove the demon spawn but things are further complicated by the story's secondary antagonist, her father Dwayne.

Pro-Life
Dwayne arrives with Angelique's three brothers armed to the teeth and demanding that the security around the clinic let them "rescue" Angelique. When a security guard refuses to admit them through, Dwayne shoots his head open and forcefully gains entrance. He and his sons wreak havoc through the clinic while trying to find and get Angelique out of there. It is shown that he has been alerted by "God" to save Angelique unborn child. Being extremely devout to his faith, Dwayne believes this is a message from the Lord and proceeds to resort to any means necessary to rescue the child.

Things only worsen as Dwayne encounters one of the doctors in the clinic and decides that he must "take justice" for all done in the clinic. He and one of his sons graphically torture and kill the doctor with a suction device, even with their "mission" in mind. As the plot progresses, the demon spawn's father appears in the clinic and begins slaughtering anyone in its path, including one of Angelique's brothers. Dwayne eventually crosses paths with the monster itself, who reveals that it was the "God" that directed Dwayne in the first place. Horrified at having been misled by a demonic force into committing horrific acts, Dwayne is killed by the Demon Father.

Aspects
While being a bit of an extremist and a fanatic, Dwayne nevertheless wanted the best for his children and was determined to rescue his daughter. While one could say that several of his villaionous actions were directed by the Demon Father (which is not a lie), he commits several acts of his own volition, such as murdering the security guard and conducting the graphic torture of the clinic doctor while he is supposed to be finding his daughter. However, he showed remorse in a "my God, what have I done" fashion at the revelation of the "Godly" voice.
