To me, it is very reminiscent of what happened to Nightmare Moon.

The Elements literally purged Sunset of all her negative emotions and desires for a few seconds. For those few moments, she was free of all that self-delusion that is a key to allowing (normal) people to do evil. At that moment, Sunset realised that she was doing the wrong thing for the wrong reasons and had become the very monster from which, according to the prequel comic, she wanted to be a Princess so that she could protect Equestria.

In Rainbow Rocks, I think that she was still uncertain of her own mental and ethical integrity. She was afraid to show anger or any other aggressive emotion out of fear that it would send her back down the Dark Path.
