Juxtaposition: What would one conclude as to the relative value of life vs book in conservative Islam?

Consider these two now old news events from Afghanistan:

First, this. American soldiers burn copies of the Koran that had been used for illegal prison communication.

Response: “If you burn the Koran, we will burn you.” Dozens killed in rioting.

Next, this. A mentally ill US soldier goes on a killing spree against innocent civilians.

Response: “The Afghan Taliban said it would take revenge for the deaths, in an emailed statement to media.” A press release.

So, what would one conclude as to the relative value of life vs book in conservative Islam?
