Is a +EV decision "no matter what" worth it by virtue of "being the right play" if it costs you nearly half of a buyin?

I saw John Duthie v Tom Dwan HU and Duthie made a very good fold, yet all the 2+2 guys were berating Duthie saying it was a bad fold, just because mathematically it was +EV (I think that's why it was anyway).
