But I'm afraid you can't fix this certain soul's humor.

And so it must.

If at a sudden point you fly into a temper and thoroughly beat the boy for hardly touching the cat--well, that's life.

All you've got to say to him is: "There, that'll serve you for all the times you _have_ pulled her tail and hurt her." And he will feel outraged, and so will you.
But what does it matter?
Children have an infinite understanding of the soul's passionate variabilities, and forgive even a real injustice, if it was _spontaneous_ and not intentional.

They know we aren't perfect.
