Evil versus lunacy: a distinction without a difference for those coping with the consequences of the wonton acts of either. You can't rescue every soul from the clutches of badness or mental illness.

Put it down to naivety, do-good-it-ness or political correctness. It's a hostile world out there - growing more so by the day. Canada can be compassionate and careful at the same time. The two are not mutually exclusive.
