I don’t condone Trusova’s behavior but I don’t think the situation compares.
Kaori came into the situation knowing that she would need help even to win bronze because her TES couldn’t compare. Bronze was her gold.
She was thrilled to be on the podium
I agree with this to an extent. Kaori had the benefit of going into the competition knowing she would need help to get on the podium. Boy, did she get it.
From our outsider's vantage point, we knew the same was true for Sasha with regard to gold - she would need help to win. But, and here's where I think it's fair to remind ourselves that she is a headstrong 17 year-old, we don't know what her support system was telling her with regard to her chances of winning. And by support system, I don't mean just the coaches but also her parents. For all we know, Eteri & Co were trying to be honest with her and she/her parents just wouldn't listen.
I've been in a similar situation, albeit not with an Olympic medal on the line, and it didn't matter how gently or candidly I or anyone else tried to get it through to the 17 year-old or her parents that their end goal was not very likely, no matter how many warning signs were obviously there and pointed out to them, they simply refused to believe that anything less than what they'd set their sights on would be the final outcome. And when the result was announced, with this youngster in front of a crowd of 200 people, where she didn't get her desired outcome, she fell apart. Her parents were just as outraged. And she had a temper tantrum meltdown for the ages. And everyone else just kind of sat there alternately feeling rather awkward about it (and I do place some blame for that situation on other adults who had more influence/control over the outcome for not being a bit more honest about this young person's chances at achieving her desired result - similar to how the judges weren't setting appropriate expectations with the over-scoring of Trusova's PCS and her non-jumping elements), and pointing out to younger teens & pre-teens present just what a poor sport the youngster was being about it.
Now, the situation isn't entirely comparable, but it's disturbingly similar, and, much as I agree that Trusova behaved very badly and, clearly, did not go into the competition with reasonable expectations, I can see how it is possible that there was simply "no talking to her" or getting it through her or her parents' heads, beforehand. Thus, her meltdown. No, it isn't excusable, but it's entirely understandable, and I can cut her some slack because I've seen kids that age absolutely inconsolable, even when all of the signs have been pointing toward a different outcome that they just refused to see going in. Hopefully, with some time and self-reflection, she'll come to recognize how poorly she behaved and how her own choices led to the result.
