Some people really do learn from classes. I'm not being facetious. Sometimes teaching you can actually see that students have never considered certain things and for them it is a revelation of sorts.

To understand this you have to also take on board that ethics is difficult. The media often gives us simplified versions of situations after the fact and we can't help but feel the "right" choice was always obvious. But in reality, as an ethical conflict develops those involved often feel helpless as the problem continues to grow. No one risks stopping it precisely because they don't have the intellectual framework to deal with or understand the developing complex ethical dilemma until it is too large for a single individual to take on.

I get where you are coming from though. I'm just saying that some people aren't lucky enough to have come from that place. Education does often make the difference for well meaning people not otherwise exposed to a good moral foundation.
