Marie meant that if Gabriel found out about his role in killing her before getting the God Mask, destroying the Lords of Shadow, and defeating Satan, he would have descended into a suicidal depression and probably kill himself out of guilt before succeding in his quest. Based on Gabriel's outlook in the Reverie DLC, I think she was right.

On a related side note: according to the Catholic Church, if you commit suicide, your soul most likely ends up in Hell.

Hope this helps!
