I don't think that is what is implied, Cote.
You could interpret it as karma playing itself out. So, if someone was the perpetrator of a heinous crime in their last life they become the victim in the next. Personally, i would find this quite abhorrent, as no doubt would the parents of any child who has suffered. Here's quite an interesting extract from Mark Albrecht?s book Reincarnation (i need to learn how to link!):
1) The person of Hitler ceased to exist at the moment of his physical death. Only the impersonal self will reincarnate, accompanied by its karmic deposit. However, there is no continuity between the person of Hitler and that of the individual who has to endure the hardships imposed by Hitler?s karma. The newborn person doesn?t know that he has to work out Hitler?s karma. After the cruel life and death of this person, other millions of reincarnations will succeed with the same tragic destiny. The most intriguing fact is that the person of Hitler, the only one who should have endured at physical and psychical level the results of his deeds, was dissolved at physical death, while other persons, totally unaware of this situation and innocent, have to work out his bad karma.
2) As a result of the hardships that have to be endured by the new incarnations of Hitler, it is almost certain that they will react with indignation instead of resignation to their situation, and thus will accumulate a growing karmic debt. Each new reincarnation of Hitler becomes a source of newly acquired karma, initiating a new chain of individuals who have to endure the consequences. Hitler himself was the one that had karmic debts to pay. Whoever he had been in a previous life, he made his karma a lot worse during the years of The Third Reich. Therefore, instead of solving the puzzle of global justice, the problem worsened. Starting with a single individual such as Hitler, we reach a huge number of persons who pay his karma and accumulate a new one. And this is just one case in human history. An attempt to imagine what happens at a larger human scale would reveal a catastrophe that could never be solved.
You do not need to see everything that happens as predetermined - i certainly don't believe that it is. Bad people will do bad things, regardless of what plan an individual (victim or perpetrator) may have come up with while discarnate. We are also part of the natural world and vulnerable to illness and accident like any other lifeform - i don't think someone contracting a life limiting illness is any way pre-ordained. I think if karma exists then it is not an invitation to sit back and leave it to fate, but an opportunity to live the best you can to ensure a better outcome next time round, to make the best of the cards you have been dealt.
Most people (away from here anyway!) don't go around gazing at their navels. If it is possible to connect to your soul then it is still a very difficult thing to do, certainly to the extent where you can discover what your life plan is (assuming for a minute that there is one). So, most of us will have no idea what our plans are. I'm pretty sure my plan was to be running the V&A and married to Rufus Sewell - but here i am in a rural backwater living with a hairy biker (not one of THOSE hairy bikers!). I kind of think if it is so hard to discover your plan then we are probably not meant to know what it is, and are just meant to live the best lives we can, doing the most good and the least harm. I could accept that those closest to you have a deeper spiritual connection and are there to help you (or maybe challenge you a bit), and you them, but i could never see it as a 'tell you what, i'm going to develop a terminal disease so you get the chance to be compassionate' kind of a plan.
