Perhaps a simpler way to see it is a polar construct seeking balance within its nature. So when consciousness in its multifaceted form bumps up against itself in many forms there many energetic imbalances taking place. These imbalances seek balance.
The best news is knowing this you don't need to live out scenarious to balance it. Deeper understanding is the way to transcend the imbalance (karma). Otherwise ignorance requires a slower path.
Even more profound is to realize that with more clarity, karma is an agreed upon notion that must be tuned into through the collection conscious and with enough clarity and understanding can be done away with altogether, instantly.
Karma is but one channel that can be tuned into. It just happens to be a popular one.
