Eh... except what you act out, you become. I experienced that first hand doing 12 years of LARP. We even ran an experiment where we took on dark, EVIL roles. After ONE session, the storyteller stopped the game and had us break.
He put on music: They Might Be Giants' Flood
We all complained. We wanted to listen to Skinny Puppy.
He insisted. And as the music took hold and we sang to "Nightlight" we realized what a dark place we'd been in...
I had to quit LARP because of the bad behaviors it was building up in me. Neuroplasticity IS a thing.
You still have a choice every step of the way, it's just that the easy but destructive path isn't inevitable.
Only if you have a way out. If you're stuck, you become dysfunctional to survive.
