Essay help grammatically

Question

Hi! I have a few technical questions for help with an ensayo I'm writing on La casa de Bernarda Alba. Mainly, is this correct?

....y voy a explorar la visión de Lorca del carácter de las mujeres cuando son negadas el amor.

is it vision? O vista? Is "the nature of women" el caracter de las mujeres"?

is is "cuando son negados" or would "de las mujeres negadas el amor" be better? also, is it "son negados" o "estan negados" and what is the difference? This is a general question, because I always use the sentence structure and often am unsure.

Thank you for the help!

Also, how would I say, "the freedom to love"? La libertad de amar? - lreynolds, Dec 10, 2013
