Jealousy alone wouldn't bring Luna to do foul things, if the character's (admittedly briefly) shown nature is any indication. (Somewhat meek, soft-spoken). The fact that the Elements of Harmony were necessary to defeat her also suggests something beyond Celestia's capabilities. If the source of the corruption that made her Nightmare Moon were trapped (the stone prison) the extended time would explain why a handful of roughly teen-age ponies could do what Celestia couldn't (she only banished Nightmare to the moon, she couldn't destroy the corruption in her).
