You can not choose to be good or bad - you're always both. Good is what you're showing, it's what people expect from you, good is right. Good is the tyrant of the moral world.
Bad is hidden, covered. It's what you're trying to keep for yourself. It's wrong. It is moral world's minority.
The photograph is showing, that the bad (or the ugly) is just the other side of the good (or the beauty). Evil is the other side of God. They are the mirror of ourselves, they're the fight exported to metaphysical world.
