Ineluctable:
not to be avoided, changed, or resisted : inevitable : an ineluctable fate [Merriam-Webster]
Noted in an interview in NewScientist (15 July 2017, paywall) with Françoise Sironi:
Helping both torturers and their victims didn’t strike you as incompatible?
Not at all. By then I had realised that to understand one, you have to understand the other. For example, a torturer inflicting sexual abuse might say, “You’ll never be a man again.” To treat the person those words were directed at, you need an insight into the torturer’s intentions. But often the victim is too ashamed to repeat this. I was ineluctably drawn to become interested in torturers.
I will have a bit more on this interview later.
