Sin and Consequences of said sin gradually separate in some respects as time progresses

The theology Hamartiology is relevant to this posting The sin was forgiven but the consequences linger on. Case in point from bible scripture would be David's adulterous sexual lustful sinning with Bathsheba, and his subsequent order to kill her husband, Uriah the Hittite. This is evident in the biblical account of the Prophet Nathan confronting David regarding said sinful actions: >(NASB1995) > >2 Samuel 12:9 > >9 Why have you despised the word of the Lord by doing evil in His sight? You have struck down Uriah the Hittite with the sword, have >taken his wife to be your wife, and have killed him with the sword of >the sons of Ammon..................................more >scripture....more..scripture.... > >2 Samuel 12:13-15 > >13 Then David said to Nathan, “I have sinned against the Lord.” And Nathan said to David, “The Lord also has taken away your sin; you >shall not die. 14 However, because by this deed you have given >occasion to the enemies of the Lord to blaspheme, the child also that >is born to you shall surely die.” 15 So Nathan went to his house. Then >the Lord struck the child that Uriah’s widow bore to David, so that he >was very sick. ..................................more >scripture....more..scripture.... > >2 Samuel 12:19 > >19 But when David saw that his servants were whispering together, David perceived that the child was dead; so David said to his >servants, “Is the child dead?” And they said, “He is dead.” 2 Samuel 12:13-14 is proof that King David confessed and repented for said sin. Furthermore, Nathan says God took his sin away which I believe is proof that God forgave King David for said sin. However, here is a subtle & nuanced point; the consequence(s) of said sin will still manifest into reality. In the aforementioned case, Nathan prophecies in 2 Samuel 12:10 that "the sword shall never depart from your[Kind David's] house". The prophecy of doom & gloom will ultimately manifest into reality when King David's son, Absalom, kills off his elder half-brother, Amnon, due to the fact that Amnon raped Tamar, Absalom's sister. Furthermore, there would be more bloodshed when Absalom tried to lead a failed violent coup against his father, King David. Furthermore, in the 2 Samuel 12:14 bible verse, Nathan prophecies that David first child born to Bathsheba will die in the child's early infancy. The following AI-generated photo might be good illustrative analogy: a) Lets hypothetically consider the yellow paint in the image above as sin. b) lets hypothetically say that the yellow paint that is splattered on the face of the man is washable if the man confesses and repents. c) However, lets hypothetically say that the yellow paint can **Never Ever** be washed off the man's blue shirt because shirt is just made of a material that can easily get permanent stains. Therefore, Sin which is represented by the yellow paint on the man's face can easily be washed if the man confesses and repents. However, Consequences of said sin which is represented by the yellow paint on the man's shirt can Not be washed because of the shirt's material just getting permanently stained, and therefore, can Not be washed off. The sin can be washed off if one confesses and repents. The consequences of sin might linger on, and may or may Not go away. Essentially the consequences of sin has to be dealt with separately. Is the aforementioned evaluation correct? Could someone please provide feedback in regard to said evaluation, and back it up with other bible scripture verses and passages?
