Mader had too less time to play with. he should have been caught a lot earlier.
As far as Roglic goes, his team worked a lot for him. So he wanted to win. It would be cruel to gift someone else's work to another person. But if he and his team had thought through( in about a minute), it would be greater value to be magnanimous( 1 in ~50 wins vs the publicity of rising above petty goals). The only thing that Roglic would be accused of is shortsightedness.
