Not certain, but I think this is right.  I'm using the proposed unnatural scale from HeroismMechanic, where more than 7 hardening requires either getting totally fucked in the head or interacting with something on the order of wormskull.)

Unnatural: 7 hardened, 1 failed (Nightmares, Necrophobia)

Violence: 4 hardened, 1 failed (Pacifism: Cannot Kill)

Isolation: 1 hardened, 0 failed

Helplessness: 5 hardened, 0 failed (Nightmares, Necrophobia)

Self: 5 hardened, 1 failed (resistant to therapy)
