features an extremely confused and shocked Juliet
who feels betrayed by Romeo
. She jumps between descriptions of Romeo, trying to land on the best description that articulates the hurt she feels due to Romeo's murdering of Tybalt.
In an effort to be specific, let's find your three arguments within the text of this monologue.
1. Juliet no longer trusts Romeo.
O serpent heart hid with a flowering face!
Did ever dragon keep so fair a cave?
From the beginning of the speech, Juliet proclaims that a darker, dangerous side of Romeo must exist beneath his beautiful exterior.
2. Juliet considers the possibility that an evil spirit has tricked her into falling in love with Romeo.
O nature, what hadst thou to do in hell
When thou didst bower the spirit of a fiend
In moral paradise of such sweet flesh?
While this feeling does not last, Juliet contemplates if Romeo was sent to deceive her.
3. Juliet is entirely confused. In this speech, Juliet compares Romeo to countless images, including a dragon, lamb and a tyrant. She does not understand how such a vile person could exist underneath a gorgeous surface, and she's trying to make sense of this deception. This confusion is an example of how Juliet is questioning everything she feels for Romeo.
