I am going to put a different spin on this.
Conviction comes before the sin. Had it not, then we would not know we sinned. A violation of Light given, A violation of conscience.
You can still have a Conscience when no scripture covers it, Like sitting through that "WHOLE" Horror movie when something in you told you 'NO' 10 minutes into it.
Rom 2:15 Which shew the work of the law
written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another
1Ti 1:19 Holding faith, and a good conscience; which some having put away concerning
faith have made shipwreck:
Rom 14:23 And
he that doubteth is damned if he eat, because he eateth
not of faith: for whatsoever is not of faith is sin.
So conviction would be something I could not do in faith, with a pure conscience. That could be anything.
This is why it's stupid to ask if something is good to do or not or scriptural. The questioning itself gives the person the answer.
Condemnation: (I assume Self-Condemnation)
Will always come after violation of Conscience, faith. This is not the devils fault, and can not be escaped if we willfully violate our conscience or conviction or Light given.
Sin carries a penalty. That is "OUR" heart condemning us before God.
And hereby we know that we are of the truth, and shall
assure our hearts before him. For if our heart condemn us, God is greater than our heart, and knoweth all things. Beloved,
if our heart condemn us not, then have we confidence toward God.
(1Jn 3:19-21)
Satan has nothing to do with this, we always have a choice to listen to him or not.
