Tris’s mom says, “Human beings as a whole cannot be good for long before the bad creeps back in and poisons us again” (p. 441). Do you agree or disagree? Why?

I agree..... it's like saying, "In a perfect world...." Unfortunately, the world isn't perfect, nor are human beings. Even the best of people make mistakes..... break the law....... and make poor choices. There are also those who prey on these tendencies and take advantage of them in others.
