We can stay with the KJV and it comes out the same, if you take the time to study how the KJV uses the singular "sin" and the plural "sins". Sin in the singular has a general and habitual meaning coming from the sin nature in man and "sins" are particular sins. Then also you must keep track of the limitations KJV contexts give us and I quote from Principles of Interpretation:
"A third kind of limitation that must not be disregarded is that furnished by parallel passages. Thus in I John 3:6, we read, "Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither knoweth him." In verse 9, the writer adds, "Whosoever is begotten of God hath no sin, because his seed abideth in him; and he cannot sin, because he is begotten of God." It would seem from these statements that John teaches that Christians never commit sins, and cannot do wrong of any kind. But when we consult 1:10, we see a clear limitation. He says to Christians, "If we say that we have no sin, we deceive ourselves, and the truth is not in us;" and so in 2:1,2, "If any man sin, we have an advocate with the Father . . . and he is the propitiation for our sins, and not for ours only, but also for the sins of the whole world." Here the apostle speaking of himself and other Christians, most clearly implies their possibility of error, and points out the way of regaining divine favor. This shows that in the first passage he means that the true Christians cannot lead lives of sin, cannot regularly practice sin; and in the latter passage he refers to occasional errors in life. Thus his terms in the former passages are restricted by those in the latter, and all are harmonious. By these examples we are prepared to state the general
RULE:—Choose the broad, meaning of a term, unless it be restricted." https://icotb.org/resources/PrinciplesofInterpretation.pdf
Keeping in context involves more than comparing the immediately adjacent verses, but the book itself.
"If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make him a liar, and his word is not in us." (1John 1:8-10, KJV)
"He that committeth sin is of the devil; for
the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil. Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother." (1John 3:8-10, KJV)
The devil practices habitual sinning from the beginning and the children of the devil do likewise. The
children of God do not practice habitual sinning.
