According to reincarnation beliefs, history tends to repeat itself until those who have participated in it learn their lessons and change for the better. This means that an individual may face identical situations from one life to the next until they are able to conquer whatever "cause and effect" chain-reaction they have caused from a previous life.
As an example, a person who "lives by the sword" in one life and dies without having made amends for his mistakes, will in the next life be faced with identical situations which must be overcome. Ultimately, such a person will have to face themselves and have inflicted upon them everything they have inflicted upon others. Divine justice in many religions shows that those who "live by the sword" will "die by the sword", if not in their present life, but likely in a future life. Reincarnation theory states that those who do not learn from history are doomed to repeat it.
The lives of President Kennedy and President Lincoln had so many parallels that it cannot be dismissed as pure coincidence. To my mind, these parallels are evidence of history repeating itself and evidence of reincarnation. To me, these parallels may be circumstantial evidence that President Kennedy was the reincarnation of President Lincoln. You decide for yourself.

It appears that history does indeed repeat itself. Perhaps it is the same cast of characters playing the same roles over and over again. Perhaps William Shakespeare said it best:
