If we had stopped just because we were scared, Malos would've destroyed the world. Fear isn't strictly a bad thing, but let it control you and you'll find everything you care about slipping away in an instant. Or worse, you just stop caring. I should know, I'm speaking from experience. I let the greatest man I ever knew die because I was afraid of people knowing I'm a Flesh Eater. Don't let that be you, Ruby.
