I'm sure he said bad things about Danya, and even now he's protecting himself when he should be just sorry for what terrible thing has happened, but generally Danya was more liked than Kramnik, so he can't be responsible / accountable for something he doesn't have power over (Danya's life).

If you are famous, you will have haters, it's part of the deal.

I agree with the crowd who say that mental health issues should be taken seriously instead of kept under the rug.
