> You're reducing a human being to a single binary classification - evil or not evil
That is correct.
> You're also saying that you're prepared to ignore the wider impact that the act of executing that individual has on society.
That must specifically not be allowed to cloud our judgment. "Society" is word which refers to collection of people, the vast majority of whom have no connection to the case.
"If only there were evil people somewhere insidiously committing evil deeds, and it were necessary only to separate them from the rest of us and destroy them. But the line dividing good and evil cuts through the heart of every human being. And who is willing to destroy a piece of his own heart?
During the life of any heart this line keeps changing place; sometimes it is squeezed one way by exuberant evil and sometimes it shifts to allow enough space for good to flourish. One and the same human being is, at various ages, under various circumstances, a totally different human being. At times he is close to being a devil, at times to sainthood. But his name doesn't change, and to that name we ascribe the whole lot, good and evil."
That is correct.
