Answer:
A villain does bad they WANT to bring harm. They delight in it with a sly evil grin on their face. They most likely used to be good but they were never good enough always bending the rules. Now they break the rules without another thought. They get satisfaction in doing bad. They may be jealous of the hero in the plot or they may be angry at the hero and want to destroy them. The villain will get people to help him with his task he will make promises that he will never keep and betray all of them. He wants power. A villain wants to ruin everything good in the hero’s life because he doesn’t have it himself. The villain may or may not have a sad story behind him it depends of what you are writing.
