on the one hand, I, the Lord your G-d, am a jealous G-d, visiting the iniquity of the fathers on the children, on the third and the fourth generations of those who hate Me,” Exodus 20:5 .
But on the other hand, “The person who sins will die. The son will not bear the punishment for the father’s iniquity, nor will the father bear the punishment for the son’s iniquity; the righteousness of the righteous will be upon himself, and the wickedness of the wicked will be upon himself.” (Ezekiel 18:20).
So basically, it’s a crapshoot whether her parents’ sinfulness will transmit to her, but the more conservative route is to heed the warning in Exodus and proceed cautiously. her mother’s evilness could transmit generations down the line!
