Something interesting
I found this that is relevant to the first part of your questions:
Ezekiel 18:1
The word of the LORD came to me: 2 "What do you people mean by quoting this proverb about the land of Israel:
" 'The fathers eat sour grapes,
and the children's teeth are set on edge'?
3 "As surely as I live, declares the Sovereign LORD , you will no longer quote this proverb in Israel. 4 For every living soul belongs to me, the father as well as the son-both alike belong to me. The soul who sins is the one who will die.
He will not die for his father's sin; he will surely live. 18 But his father will die for his own sin, because he practiced extortion, robbed his brother and did what was wrong among his people.
19 "Yet you ask, 'Why does the son not share the guilt of his father?' Since the son has done what is just and right and has been careful to keep all my decrees, he will surely live. 20 The soul who sins is the one who will die. The son will not share the guilt of the father, nor will the father share the guilt of the son. The righteousness of the righteous man will be credited to him, and the wickedness of the wicked will be charged against him.
21 "But if a wicked man turns away from all the sins he has committed and keeps all my decrees and does what is just and right, he will surely live; he will not die. 22 None of the offenses he has committed will be remembered against him. Because of the righteous things he has done, he will live. 23 Do I take any pleasure in the death of the wicked? declares the Sovereign LORD . Rather, am I not pleased when they turn from their ways and live?
