Of course this is not always karma (true what others mentioned).
Also, we are reborn to learn our own lessons, and by my belief we are the ones who choose our own path suitable to our soul evolution.

When we come here we are not suppose to remember our past lives and what we have been in the past should not determine how good a person we can be now. If we knew all that was before - how could we learn our lessons properly? This would be like cheating on the exam papers...

Though there are cases when people remember their past life or lives, but they sure have some special task for that.
