An emphasis on moral behavior (and the questioning of it) is at the core of "Romeo and Juliet". The main conflict revolves around it: how ethical it is to fall in love with my family's enemy? During the course of the drama, this moral question transforms into another one: How ethical it is to hate other people in the first place, based only on their surname?
The ethical question gets especially complicated when Juliet thinks about marrying Paris. To her, it seems as if she would betray Romeo, which she would never do; but the paradox is that if she betrayed Romeo, she would undo the betrayal of her family. In spite of that, she doesn't want to give up on her loyalty to Romeo. In Act 4, Scene 1, she says:
JULIET
O, bid me leap, rather than marry Paris,
From off the battlements of yonder tower,
Or walk in thievish ways, or bid me lurk
Where serpents are. Chain me with roaring bears;
Or shut me nightly in a charnel house,
O'ercovered quite with dead men's rattling bones,
With reeky shanks and yellow chapless skulls.
Or bid me go into a new-made grave
And hide me with a dead man in his shroud
<span>(Things that, to hear them told, have made me </span>
tremble),
And I will do it without fear or doubt,
<span>To live an unstained wife to my sweet love.</span>
<span>"He had come forth from the hands of God a perfect creature, happy and prosperous, guarded by the especial care of his Creator." => Adam. Adam is God's special creature, created with utmost care and love, a perfect being that was supposed to rule the Earth and be happy. His tasting of the forbidden fruit brought an end to his happiness and signaled a beginning of toil.
</span>"like him, when I viewed the bliss of my protectors, the bitter gall of envy rose within me." => Satan. One of Satan's crucial features, which ultimately resulted in his banishment, is his envy upon all God's angels and God himself.
<span>"A new species would bless me as its creator and source; many happy and excellent natures would owe their being to me." </span>=> God. He is the only creator and source of everything.
