The character who says, "Beguil’d, divorced, wronged, spited, slain./ Most detestable death, by thee beguil’d" is Romeo in William Shakespeare's "Romeo and Juliet." However, since that particular line doesn't match perfectly with known text directly, it appears to be paraphrased. If you're looking for a character that speaks on themes of betrayal and death in the context of love's tragedy, it involves key figures like Romeo or Juliet expressing despair over their circumstances.
If you are looking for the options you provided to be matched specifically, please note that none of the listed characters (Paris, Lady Capulet, Nurse, Friar Lawrence) says that exact line.
