Steal the goose, and give the giblets in alms.

The proverb criticizes someone who takes something valuable and then gives away a small part of the proceeds as an act of charity. The gift does not undo the theft.

It also points to the appearance of virtue: a person may seek credit for generosity while ignoring the harm that made the gift possible.

Use it to criticize a charitable gesture funded by wrongdoing, especially when the giver keeps most of the benefit. The emphasis is on the contrast between a serious wrong and a much smaller public good.
