Some weeks seem more tumultuous than others, and this week, across the globe, we have witnessed much trauma.

I am thinking, of course, of the thousands of people who have died or been injured or left homeless in Nepal and surrounding areas in the avalanches and destruction caused by a major earthquake. I am thinking also of the two Australian men, Andrew Chan and Myuran Sukumaran, who were executed in Indonesia for their drug trafficking crimes, along with six people from other countries.
