The answer for this comes in the Acela Sutta (although this quote comes from here). Of course, the question was phrased differently by Kassapa, but the essence of the question is the same.
Again, when the Buddha was asked by the naked ascetic Kassapa whether suffering was of one's own making or of another's or both or neither, the Buddha replied "Do not put it like that." When asked whether there was no suffering or whether the Buddha neither knew nor saw it, the Buddha replied that there was, and that he both knew and saw it. He then said "Kassapa, if one asserts that 'He who makes (it) feels (it): being one existent from the beginning, his suffering is of his own making,' then one arrives at eternalism. But if one asserts that one makes (it), another feels (it); being one existent crushed out by feeling, his suffering is of another's making,' then one arrives at annihilationism. Instead of resorting to either extreme a Tathaagata teaches the Dhamma by the middle way (by dependent origination)".
The second useful sutta is the Acintita Sutta which states that the precise working out of karma cannot be conjectured:
"The [precise working out of the] results of kamma is an unconjecturable that is not to be conjectured about, that would bring madness & vexation to anyone who conjectured about it.
The third useful quote below comes from the Sivaka Sutta, teaching that not everything we experience in life is due to karma. Some times it's due to the weather or indigestion etc.
As he was sitting there, he said to the Blessed One, "Master Gotama, there are some brahmans & contemplatives who are of this doctrine, this view: Whatever an individual feels — pleasure, pain, neither-pleasure-nor-pain — is entirely caused by what was done before. Now what does Master Gotama say to that?"
[The Buddha:] "There are cases where some feelings arise based on bile. You yourself should know how some feelings arise based on bile. Even the world is agreed on how some feelings arise based on bile. So any brahmans & contemplatives who are of the doctrine & view that whatever an individual feels — pleasure, pain, neither-pleasure-nor-pain — is entirely caused by what was done before — slip past what they themselves know, slip past what is agreed on by the world. Therefore I say that those brahmans & contemplatives are wrong."
"There are cases where some feelings arise based on phlegm... based on internal winds... based on a combination of bodily humors... from the change of the seasons... from uneven care of the body... from harsh treatment... from the result of kamma. You yourself should know how some feelings arise from the result of kamma. Even the world is agreed on how some feelings arise from the result of kamma. So any brahmans & contemplatives who are of the doctrine & view that whatever an individual feels — pleasure, pain, neither pleasure-nor-pain — is entirely caused by what was done before — slip past what they themselves know, slip past what is agreed on by the world. Therefore I say that those brahmans & contemplatives are wrong."
