Was it a violent rape? Or was it ~~a concensual get together but she was far too young and he was slapped hard for it~~ statutory rape because young children cannot consent?

FTFY. It was statutory rape. He groomed a 12 year old, and slept with her multiple times. It wasn’t just a spur of the moment thing; It was planned, and he went out of his way to convince the victim that having sex was her idea.

On one side, he, and society overall see it as he served his sentence (not all of it but that is not his fault)

To clarify: He was sentenced to several years where the crime happened, but was extradited to his home country after only a few months. After extradition, he didn’t serve any time. So he only served a few months total.

and is rehabilitated

He had repeatedly refused to even acknowledge it during the games, and tried to downplay it every single time he was directly asked. Not even so much as a “yeah I messed up but I’m doing my best to make up for it.” Just straight up refusal to engage. Refusing to even admit you messed up doesn’t really tell the public “yes this person has been rehabilitated.” And again, he only served a couple of months for the crime.

he made changes to his life after that and made sure he is not near minors alone again

The Olympic Games are mostly minors, and most of the athletes live and sleep in close proximity to one another for the duration of the games. The Olympics are also pretty notorious for the massive orgies that happen after hours. They even have special beds (which the athletes always complain about) designed to only hold the weight of one person, because they couldn’t find better ways to stop all the athletes from having hardcore sex parties every night. Almost as if cramming a bunch of the world’s most physically fit teens into a close space and forcing them to sleep in one giant hotel will lead to rampant sex.
