Wow bukowski so profound do you also bathe fully clothed you dickhead. “Oohh isn’t it funny that a person will eat when they’re hungry but will duck if you throw an apple at their face”
Give them Motive
Make them damaged, make them scarred, make them completely out of their minds! Anything to create a motive. Motive is everything… At first. If your character is so damaged that they don’t really need to have a motive (I’m looking at you, Joker) then make them absolutely INSANE. But if you want one that your readers can and will connect with, give them a reason.
Backstory can be a big deal. If you can, give them the reason why they became the reason the way they were. Now, sometimes you don’t need to really type out what happened because your readers will just automatically know. But if you get the chance to give your readers a peek into the mind of your antagonist, leap at that chance. This will make them love (or hate) your antagonist even more than they already do, or it could change their views entirely and change their minds about your character
Getting Up Close and Personal with the Protagonist
Don’t you dare tell me that you don’t love these scenes. The villain and the hero, up close and personal, so much tension you can practically taste it, but you don’t care. We long for these moments. Don’t pretend you don’t love it. We all do. Write one of these bad boys in there and, if you can pull it off, you’ve got yourself at least one reader who likes the villain a little more than the hero.
Rare Moments of Innocence
This isn’t going to work for every villain, but for that one moment when the villain becomes the hero and it’s just so full of feels… It’s perfect. Typically works better if you already have some emotional connection to the character.
