Is death the end of the road or the beginning of a new life?

A person leaves, then comes back, then leaves again... and so on, in a circle, but the most interesting thing is that this circle can be broken, but it's unclear what the meaning of that would be. Positive and negative actions accumulate over many lifetimes, but the catch is that the person doesn't know what leads to positive or negative outcomes, which is why they wander from one life to another, often with their lives remaining practically unchanged. It's like in one episode (about a police officer) of the movie "The House That Swift Built."
