Now... I could be a cheeky little bugger here and say 'Ataraxia' as it the word in the title of 'Journey to Ataraxia' and a good tip on the phylosophy I employ in my writing.
But I won't ^^
Instead I chose CAUTERIZE a lot of this story is about wounds, both heroes and villains alike have deep wounds that unable to heal... either phsically, emotionally or mentally... Wounds that were left untreated and neglected for so long they festered and made them sick.
Cauterize is perfect here, because it is not an easy nor painless process... IT BURNS! and even when its for their own good, people will kick and scream! And it's ugly to witness and makes you feel wrong sometimes, but nescessary to deal with some of the more terrible stuff they went through... And will still go through as the story moves on.
I use an analogy for this inside the story called the flame of truth... And without spoiling much, that is exactly what it does... It burns those scars and closes the wounds so that characters can move foward in their search for the ever elusive 'peace of mind' in the title
