How does the quote “Ethics is knowing the difference between what you have the right to do and what is right to do.” relate to Ethics?

imparadis't in one anothers arms  

the happier eden, shall enjoy their fill  

of bliss on bliss, while i to hell am thrust,  

where neither joy nor love, but fierce desire,  

among our other torments not the least,  

still unfulfill'd with pain of longing pines;  

yet let me not forget what i have gain'd  

from their own mouths; all is not theirs it seems:  

one fatal tree there stands of knowledge call'd,  

forbidden them to taste: knowledge forbidd'n?  

suspicious, reasonless. why should their lord  

envie them that? can it be sin to know,

this question is grammatically incorrect and is illegible to me so i can not answer.

you can buy 12 peppers or less. $1.50*12 = $18
