Who is to blame for all bloodshed in Macbeth?

This is for my English HW someone help!!

The witches and the apparitions, the own insecurities of Lady Macbeth and Macbeth and misplaced attempts to control his future led Macbeth to become the most responsible for the bloodshed in Macbeth's story. The witches and their prophecies have been a superior effect upon the actions of Macbeth.

either a donut or a sphere or a pancake or a flat sphere. it depends on where the vertical line is.

if the line goes through the center of the circle and is perpendicular to a diameter containing the center, then you get a flat circle.

if the line and the diameter of a the circle meet in the center of the diameter and at an angle, you get a pancake.

if the line is on the circumference of the circle and is at right angles   to the circle you get a ring.

if the line contains the diameter, you get a sphere.

the the line is parallel to the diameter and touches the circumference, you get a donut.
