Hidden depths contradiction

By Tokichii, in Mansions of Madness

So I played the hidden depths scenario today and without spoiling anything it went great. However at the end one of my friends told me his agenda card didn't match the prompts given in-game. He swears it told him his goal was to make sure as few survivors make it out despite his agenda being human.

I'm wondering in situations like this do you follow the app, or the agenda card?
