Evil vs Good

Ive recently started reading "Lucifer Effect", which is a study on college students placed in a set up prison as guards and prisoners, there behaviour is monitored, to see how evil is arroused in individuals, relating specifically to environmental forces, and how each individual takes on a role, i am not far into the book, although will keep you updated on what happens.

Have you ever seen your loved one or yourself change because of the situation you are in, taking on a role that suits the situation?

Becoming apart of a group instead of being an individual?

Doing evil things, or things that are beside you?

If you have read the book or are in the process of reading it, leave a comment, let me know what you think, and what are your experiences are regarding the above questions?

A must read to gain an understanding of social context.
