The game's plot, especially its ending, may be deeply triggering to trauma survivors. Basically, the Maw exists because of Lily's childhood sexual abuse trauma, and the last scene has her tell the protagonist to kill her because the curse will only spread while she is still alive. While it's ambiguous whether Marianne does kill Lily or sacrifices herself, it's often interpreted as 'trauma survivors are lost causes and will only ever spread their trauma' ('you can't always save everyone', the game tells us). This is not helped by an earlier reveal that Lily's abuser is also revealed-- in depth-- to also have childhood trauma resulting from the Holocaust, loss of a loved one, and domestic violence, resulting in a monster of his own. It's clearly attempting a 'trauma often leads to more trauma' narrative, but it's generally agreed to be mishandled.
Though the assault itself is not depicted directly, the game has in part to do with the trauma of child sexual abuse by a close family friend. It it referred multiple times.
**Spoilers**
The protagonist's father is taken and experimented on by the Nazis. AFTER his escape; though he leaves the protagonist at a hospital he keeps her sister who ends up being locked up indefinitely in an underground bunker where she's sexually assaulted by a family friend. SO while he doesn't directly "kidnap" his own daughter. Keeping prisoner, isn't an option, leaving this the best place.
