character of Angelo
Angelo is the arch-villian of the play. When the duke puts him in command of Vienna he proves to be cruel and hypocrritical ruler and upon the return of the Duke he is punished.
Strictness is one of defyning characteristics of Angelo troughout the whole play. Also, he reveals himself as a hypocrite because he doesn't judge himself as he does others. In act 1, scene 4 the Duke describes him:
-Lord Angelo is precise;
Stands at a guard with envy; scarce confesses
That his blood flows, or that his appetite
Is more to bread than stone: hence shall we see,
If power change purpose, what our seemers be.
