Healthy relationships are important, but Type 7's condition is more layered. This is not a two-way redemption, this is a two-way journey of illness.
The heroine suffers from White Knight Syndrome, and the condition of the ruffian boss needs no elaboration.
They are souls that need to entangle and eat each other. They are the fruits of blood and betrayal, curses and blessings.
That is by no means salvation, but a slow decline of decaying sickness.
When Perturabo resurrected Callifon again and again, he was destroyed again and again because she was not real after all.
When he tastes the memory and sacrifice of Callifon, and when his soul also emits a hungry thirst, he will understand that this is not redemption, but the eternal pain and love that Callifon gives himself.
There are also the famous mentally ill Konrad, Horus, Lorgar and other mentally unhealthy primitives behind. This is not salvation, this is more painful than love, and deeper than hatred.
Purpose: To live with hope in despair
