Well he had the power do cause all the chaos he wanted in Keep Calm but couldn't throw his friendship with her away so the Elements weren't even an issue there at first. Twilight said friendship was something once he had he didn't want to lose. Of course he also knows he'll be turned to stone if he returns to his evil ways, and did seem to be thinking something evil when he learned that the Elements were gone, but Fluttershy reminds him that their friendship ends if he does anything evil again. He might be a little more mischievous, but won't let it reach an "evil" scale or get too out of control.

And if Discord does decide to become evil again, maybe the box contains a new weapon to act as replacement to the Elements of Harmony, which could destroy him. It would be another retcon on what we thought his personality was, but others might embrace that he returns to the Discord they loved from The Return of Harmony
