“[S]urely it is much worse to drown a piglet in a pond than to merely walk past her, letting her drown? But to the piglet, the result is the same.

To anyone who is suffering, it makes no difference whether that suffering is caused by deliberate action or unintentional neglect — they suffer the same either way.”
