Each person is responsible only for his or her own sins. Even the Christian doctrine of 'original sin' does not mean that humans are punished for the sin of the first human pair but, rather, that humans seem inevitably to copy the sin of the first human pair.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.
