each man is held accountable for his own sins.
Ezekiel 18:20
[SUP]20 [/SUP]The soul who sins shall die. The son shall not suffer for the iniquity of the father, nor the father suffer for the iniquity of the son. The righteousness of the righteous shall be upon himself, and the wickedness of the wicked shall be upon himself.
Why was it that David's and Bathsheba's baby died in 2 Samuel 12?
