What is the duty of care for others?

The force of example, I repeat it, is terrible, terrible! and the responsibility of all, therefore, is great with whom influence rests in a special way, as it does with those, for instance, to whom the young are taught to look.

That is why there are so many here who had charge of children, parents, guardians, teachers, nurses, innumerable. 

They go to hell first, of course they do, but they are followed by many of those whom they should have taught the way of life. And not only are they followed by them, but by their children after them, generation rising against generation in awful accusation.

I am one of the worst of those who dare not lift their head, so I may well speak in warning! I know what awaits me.
