Of War and Lies

Liar is a four letter word. It means a person who leads you to believe something that is not true.

Four little letters, plastered on my back like a brand. Nobody trusts me. I guess it's for the best.

Nobody tells you when you're born what you're going to be when you're older. Well, they might. They're usually wrong. I know from experience.

Who am I? Well, I'm a GOD of course!
