By all accounts, Tiller dealt with these horrific situations with dignity, compassion, and grace, helping women and their families deal with the loss and grief that always come with being faced with such a traumatic decision. He didn't just tend to their physical condition; he tended to their psychological and spiritual well-being, too. Most of us will be backed into life-or-death corners regarding serious medical conditions (a family member's, or our own) at some point in our lives. In those times, we are fortunate when we can find doctors with that kind of ability to understand the nuances, and help us deal with the ambiguities, and come to terms with the hard decisions we must make. Tiller was, according to his patients, one of those doctors.
This is the man you killed today.
