If you play an evil character it’s gotta stick a little.
And if you’re a character-actor who always gets the evil role. If you play 100 evil guys. Then 100X moreso.
You get into the evil role. See the world through evil eyes and evil motivations.
And over time it’s gotta bend your personality towards real evilness. Right?
I suppose you could google evil-character-actors. 20 years later, how many got arrested for something heinous.
What do you think?
EDIT
Put more generally : Can habits gained in one context bleed over into another context?
Yes.
Do they?
Possibly. With increasing probability as the habit becomes stronger. And there’s self-awareness to consider. And how much the habit clashes with the new context.
From a larper perspective (so way more immersive than acting, and I played in amateur theatre and short movies) no.
Everybody understands that we need a villain for a story (even the Barbie movies has to break the Barbietopia tomake a fun movie) and being a villain on set (or in game) doesn’t mean you’re one in real life. A good larp villain need to be a fundamentally nice person, and take care of other players while insulting/torturing/assinating others.
