 I had a hard time finishing this book which lowered the stars I would have given it. However, the ending was something I loved yet it was very bittersweet. I imagine this is how I feel when I will try my first 85% dark chocolate - something I love and hate but I will swallow it all; embrace it all. 
 //SPOILERS// 
 I really disliked the fact Roth brought in "genetically damaged" because it made it seem like they weren't good enough due to their genes. Something so minute that even our naked eyes cannot see can cause such a rift between people. Yet I can understand why she chose this because I can try to see all the perspectives that was thrown at me. 
 At one point, I feel like the scientists behind all this GP, GD business should have factored in nature versus nurture but I also realized that maybe nurture is not scientific enough for them. However, because they fail to factor that in, they will never understand that even if they are "genetically damaged", they canstill be inherently good, inherently capable of all things they that "genetically pure" can do - just like How Tris can see Four do. But scientists fear changes and anything that may interfere with their logic of thinking, they should toss away since it is all blasphemy anyway. 
 Let's talk about the ending. It was tragic, yes, but I feel like that is the best way she could have ended it. A naive part of myself wishes that Tris could have survived but if she did, it would not make the ending beautiful. It would have made the ending like any Disney ending where they would live happily ever after but it would not make any sense. They can't live happily ever after just like in Mockingjay between Peeta and Katniss. They could only live and heal with time - like Tobias said in the end, "We can be mended. We can mend each other." These lines can be said of a lot of things and they are powerful; at least to me. It just all takes time - whether it be days, months, years, decades. 
 I am glad that I finished the story instead of allowing the parts I hate deter me from this ending.
