There are several good quotes that could be used to help illustrate that Macbeth is a villain. Some of the best ones come near the end of the play after it has become clear to everybody that Macbeth is a tyrant and getting worse by the day. His methods of keeping power are far from admirable, and in Act 4, Scene 3, Malcolm has the following to say about Macbeth. 

This tyrant, whose sole name blisters our tongues,
Was once thought honest.
A bit later in the same scene, Macduff expresses his own thoughts about the villainous Macbeth.  
Not in the legions
Of horrid hell can come a devil more damned
In evils to top Macbeth.
By this point in the play, it's clear that Macbeth is a villain and a horrible person. His actions have proved it time and time again, but audiences are alerted early on in the play that Macbeth has great potential for vile acts. In Act 1, Macbeth is already presented with the possibility of being king. He is surprised that he would consider murder, and he tries to put the thought out of his mind; however, by Act 1, Scene 4, Macbeth is convinced that the throne is his for the taking, and the end justifies the means. 
The prince of Cumberland! That is a step
On which I must fall down, or else o'erleap,
For in my way it lies. Stars, hide your fires;
Let not light see my black and deep desires.
The eye wink at the hand, yet let that be
Which the eye fears, when it is done, to see.
