OP is not denying the existence of karma and its propagation to the next life. He is wondering how it works exactly. This is where we have to look to the most famous spiritual scientist of our time, Albert Einstein, for insight. who said “Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect, as well as for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper.”

He admits that the forces governing karma care outside our control, implying a predetermined universe. 

Right. This passage I'm quoting is a mechanistic description of karma which is why I shared. Setting aside the question of control, karma is generated based on our actions.
