The Meraglim: What is Wrong with Following the Leaders?

Parashat Shelach deals with the Sin of the Spies. It is important to flip back and forth between our Parasha in Bemidbar and the account in Devarim to gain a fuller picture, so we will be looking at both stories see how the Torah depicts the turn of events. The meraglim (spies) have a prominent place in the sin, but the entire nation is punished. We explore the nation's role in the sin, It is easy to be led astray by the leadership -  what is so bad about the nation listening to the majority of the leaders? Why does this bar them from entering the land? 

In Bemidbar it becomes apparent that the nation  has never really gotten over slavery- they look for any excuse not to proceed to the Promised Land.
