So...
I had a thought that's been on my mind that sort of ties is to what
@Shishœ mentioned a while back about what makes a villain beyond the point of redemption and what makes a villain's ambition more "sympathetic" than the hero's.
That made me think of the different kinds of villains in fictional works and how a writer goes about creating their character in a certain way to elicit a certain emotional response from the viewer/audience.
Some write their villains to have sympathetic motives or have a sympathetic backstory to them to make the readers feel sorry for the character. This is usually done when the villain's backstory is one filled with tragedy, misery, and whatnot.
And then there's the kind of villains that are written in a way where the writer wants you, the audience to absolutely hate/despise said character and does everything to make them unlikable; often times doing everything they can to make the characters have the least amount of likeable qualities. This is done in various different ways like having the main villain destroy the lives the hero cherishes or just making the hero's life a living hell in general.
These are the kinds of villains who I like the best in the story IMO. Those are the ones who truly serve their purposes well of serving as a foil to the main protagonist and don't overshadow the main character by being "too cool" or "too much of a badass" which usually makes the audience have a kind of; shall we say a certain "fondness" for the villain because of their cool actions. That's a sort of "trap" I think villains fall in to when they become more relateable to the viewer than the hero.
Of course even though my preference is with the latter, there is no objective "better" type of villain. I like my sympathetic villains when done right even though I appreciate the truly despicable ones a lot more for the reasons I mentioned above. And that's not to say that these two are mutually exclusive of course. I just like it when a villain is full on evil with little to no redeemable traits.
So my question to you guys is what type of villain is your favorite and why?
And also how would you go about writing a villain that you don't want the viewer to like at all? Like doing everything you can to make the viewer hate said character and eliminating any traits a viewer might find "cool" or "appealing" about the character?
