Very few Jedi were capable of using and mastering Force rage without falling to the dark side, one of the few examples is Jaden Korr. Therefore, the rage could give the wielder an instantaneous physical and mental response, but pull them into deep depression, physiological harm and the endless void of the dark side.
If light side Force-users wielded Force rage, it could disrupt their connection to the light side unless something happened to interrupt the rage and bring them out of the dark side's grip. However, the body could not handle such rage for long periods of time, so the user became greatly weakened for some time after the rage subsided. The user could then channel the anger to increase his/her own strength, speed, agility, endurance, stamina and ferocity. The Force-user would tap into his/her innermost fears, pain and hate, and convert them into an intense rage. Force rage, also known as Dark rage, Force Enrage or Force Fury, was a dark side Force ability.
