Evil can't be good (a avengers fanfiction)

my name is Winter Ivy. I'm Evil. and I'm not saying that as I've been called a bitch. I mean i am truly evil. you all read stories about heroes but you never hear the villian side of the story.
I have the ability to make illusion a reality. any illusion i create, i can make real with a single flick of the wrist. and I'm the deadliest assassin you'll ever meet. but what happens when the hero boy that's supposed to stop you, falls for you.
what happens when you fall for the enemy, will you kill them to ensure your own survival or will you give up being evil? or will the hero give you a third option.
I refuse to be something i am clearly not. despite what heroes want to think, evil can't be good. a bad girl can do good but underneath the disguise, your still evil.
