How much can 11th graders handle?

Phil Zimbardo's TED Talk on the psychology of evil and heroism is powerful. I'm thinking about using it for a unit on Cause and Effect as it addresses the issue of root cause as systemic or individualistic. Please watch it and let me know (via the poll above or in comments) whether you think it would work for 11th or 12th graders (17-18 yrs old)
Thank you very much!!!
