If the devils are chained during Ramadan, why do some Muslims still engage in actions that are not in keeping with Islam?

If some Muslims commit acts during Ramadan that contradict the teachings of Islam, this stems from their own selves, which are inclined toward evil and incite them to wrongdoing. Allah Almighty says, “And I do not absolve myself. Indeed, the soul is ever inclined to evil, except those upon whom my Lord has mercy” (Quran, 12:53).
