Macbeth Soliloquy

I'm a mad man. This is not me! I've just killing my good friend King Duncan when he has done me no harm. There's no turning back now, too late for appologies and second thoughts. The deed is done and I have to move on. My lady wants it all, happy wife, happy life. Okay Macbeth, you have to be a man and follow what the witches proficise. But hey, at least I get to be King. All the fame and riches, I get EVERYTHING to myself. I'm getting high on evil, It's my drug that I cant get rid of. If I remember correctly, the witches said that Banquo's sons will be Kings but never my offspring?! They need to be killed as well and right away! Just think about what I could have if I just finish it myself. I'd rule the world!!!
