A change made only to stop the pressure reverses itself the moment the pressure comes off.
Pain and pleasure drive every choice, and one driven purely by the pain currently in the room has a lifespan exactly equal to that pain. Relief arrives, the leverage vanishes, the belief underneath was never touched, and the old behavior returns without anyone deciding to bring it back.
Taking the freed back is worse than never freeing them, because it teaches everyone watching, the owners included, exactly what their word is worth. A vow made before God with the siege at the wall and dropped when the army withdraws was a bargain priced at the moment. A person who reforms under pressure and reverts in comfort learns to distrust their own promises, and eventually stops attempting anything that takes longer than the crisis did.
