"admitted" is very different to "confessed" IMO
The former is what someone does when they have been caught.
Agreed.
My purpose in referring to it was that he acknowledges what he did was illegal and wrong, not that he is fully remorseful (as a regular human being with a conscience would be).
The victim, perp and court all agree it was wrong and illegal, so speculation about her being near the age of consent is moot.
