No, the Apostle tells us precisely who
1 John 1 was written to beginning with the opening phrase of
1 John 2:1, and in the following 14 verses as well.
1 John 1 was addressed to "believers" (of all levels of maturity in the church),
NOT to unbelievers (as the Apostle makes clear for us, and as I pointed out clearly in my first post here:
Confessing Sin!).
Just in case you missed them, here again are the words of St. John:
1 John 1
8 If we say we have no sin, we deceive ourselves, and the truth is not in us.
9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
10 If we say we have not sinned, we make him a liar, and his word is not in us.
1 John 2
1
My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous.
2 He is the propitiation for our sins, and not for ours only but also for the sins of the whole world.
3 And by this we know that we have come to know him, if we keep his commandments.
4 Whoever says “I know him” but does not keep his commandments is a liar, and the truth is not in him,
5 but whoever keeps his word, in him truly the love of God is perfected. By this we may know that we are in him:
6 whoever says he abides in him ought to walk in the same way in which he walked.

Beloved, I am writing you no new commandment, but an old commandment that you had from the beginning. The old commandment is the word that you have heard.
8 At the same time, it is a new commandment that I am writing to you, which is true in him and in you, because the darkness is passing away and the true light is already shining.
9 Whoever says he is in the light and hates his brother is still in darkness.
10 Whoever loves his brother abides in the light, and in him there is no cause for stumbling.
11 But whoever hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.
12 I am writing to you, little children,
because your sins are forgiven for his name’s sake.
13 I am writing to you, fathers,
because you know him who is from the beginning.
I am writing to you, young men,
because you have overcome the evil one.
I write to you, children,
because you know the Father.
14 I write to you, fathers,
because you know him who is from the beginning.
I write to you, young men,
because you are strong,
and the word of God abides in you,
and you have overcome the evil one.

p.s. - I sorry to keep harping on this Shaheem (quite frankly, I'd rather just agree to disagree), and I'm really not trying to be contrary (as I believe, along with you, that our sins were all atoned for at the foot of the Cross), but I think there is more to this command that we may know (IOW, the command for believers to continue to ask for the forgiveness of their sins), or God wouldn't have made it. The fact that the command was given is enough for me to want to obey it, whether or not I know and/or fully understand the reason why it was given
James 5
13 Is anyone among you suffering? Then he must pray. Is anyone cheerful? He is to sing praises.
14 Is anyone among you sick? Then he must call for the elders of the church and they are to pray over him, banointing him with oil in the name of the Lord;
15 and the prayer offered in faith will brestore the one who is sick, and the Lord will raise him up, and if he has committed sins, they will be forgiven him.
16 Therefore, confess your sins to one another, and pray for one another so that you may be healed. The effective prayer of a righteous man can accomplish much.
