How intense is De Verraders really? Contestant needed therapy after filming

We watch it as entertainment, but behind the scenes it sounds way heavier. Roelof Hemmen said the constant lying, distrust, and emotional pressure actually got to him during the game. After being exposed as a traitor, he even needed to speak to a psychologist to process everything. Kind of wild that a reality show can hit harder mentally than something like survival shows. Do you guys think the show is too intense, or is that what makes it so good?
