https://en.wikipedia.org/wiki/Purge
In history, religion and political science, a purge is a removal of people who are considered undesirable by those in power from a government, another organization, their team owners, or society as a whole. A group undertaking such an effort is labeled as purging itself. Purges can be either nonviolent or violent; with the former often resolved by the simple removal of those who have been purged from office, and the latter often resolved by the imprisonment, exile, or murder of those who have been purged.

Cortar na propria carne é o atitude de fazer ate arriscar doer em si mesmo. Eu ia usar o mesmo sentido em ingles "without the attitudinal practice of making it hurt."

Without demeaning the suggestions from my honorable co-PROZers --and to spice the pot--- a) without the attitudinal practice of letting go (on the down/mild side) or b) without the attitudinal practice of offering a pound of flesh (on the over-the-top/Dante/Shakespearean side)
