Comment on the structure of novel, referring to examples and evaluate the impact of the structural devices on the reader.

This is an excerpt from a great site on exactly what you are asking. I'll provide the source-link below.

The Handmaids Tale is a narrative that challenges the absolute authority of Gilead, highlighting the significance of storytelling as an act of resistance against oppression, thereby making a particular kind of individual political statement. It may help when reflecting on Offred’s narrative to review Atwood’s comments :

“I’m an artist … and in any monolithic regime I would be shot. They always do that to artists. Why? Because the artists are messy. They don’t fit. They make squawking noises. They protest. They insist on some kind of standard of humanity which any such regime is going to violate. They will violate it saying that it’s for the good of all, or the good of the many, or the better this or better that. And the artists will always protest and they’ll always get shot. Or go into exile.”
