Why did Macbeth decide to kill King Duncan

In Shakespeare’s time stereotypes of men and women were that men were strong and powerful while women were weak and passive. Lady Macbeth was not weak and passive; she was strong and powerful like the men.

At the start of Act 1, Scene 2 Macbeth is shown brave and loyal with the quotation “For Brave Macbeth”, but towards the end of the scene it shows him turning into a vicious and brutal murderer when he himself kills King Duncan.

The witches are partly to blame for Macbeth’s actions because they made Macbeth think that he would be King if he killed King Duncan. They made him a brutal murderer from a loyal servant. At that time Shakespeare’s audience believed that the witches could see into the future and it would be their fault if anything happened.

Lady Macbeth is partly to blame because she also changes his character from a loyal servant to a brutal murderer, She persuades and manipulates his to kill King Duncan by saying “I have given suck, and know how tender tis to love the babe that milks me. I would, while it was smiling in my face, have pluck’d my nipple from the boneless gums, and dash’d the brains out, had I so sworn as you have done to this” In Act 1 Scene 7.

Macbeth is also to blame for his actions because he allowed
Lady Macbeth manipulate and persuade him to kill the King. I believe that the if Lady Macbeth hadn’t constantly kept on at Macbeth about the witches’ prediction then Macbeth would have waited for nature to take its course. By Macbeth being influenced by his wife I think that he wasn’t very strong willed and easily manipulated, as men in those days were known as strong and powerful while women were weak and passive. Lady       Macbeth was different and had her own opinions on life and how she wanted to become Queen.

In my opinion I believe that the witches are the most to blame because if they hadn’t meddled in Macbeth’s life by predicting the future then the King and innocent people wouldn’t have killed and nature would have taken its course.
