News footage of the terrorist bombing on 7 July 2005 highlights the number of people who were killed that day. Among the dead was a young woman, Jenny. Her mother, Julie Nicholson, was an ordained priest but quit her position because she could not forgive the suicide bomber who murdered her daughter. Julie justifies her stance by asserting forgiveness depends upon the guilty party requesting it. The person who killed her daughter is dead and so there's no relationship to be restored. She thinks Jenny would want her to lead a good life and not worry about forgiveness.
Divide the class into two groups. Give one group the proposal, 'we agree the mother should not forgive' and the other group the statement 'the mother must forgive because she is an ordained priest'. The two groups should then proceed with a debate based on these positions.
