Ezekiel 18:20, 24

The person who sins is the one who will die. The child will not be punished for the parent’s sins, and the parent will not be punished for the child’s sins. Righteous people will be rewarded for their own righteous behavior, and wicked people will be punished for their own wickedness.

However, if righteous people turn from their righteous behavior and start doing sinful things and act like other sinners, should they be allowed to live? No, of course not! All their righteous acts will be forgotten, and they will die for their sins.
