Is it ethical for one head of a hydra to lie toanother head?

nothing particularly wrong with it but seems unnecessary. if what is essentially misleading yourself could ever have merit that should necessitate that your perspective was biased to begin with and fixing that would be a much better use of time. otherwise what would it change?

thought experiment: traumatise yourself and split an alter or create a tulpa or whatever method you'd like, try playing with and lying to them in a mafia game and see what happens. chances are you'll find it's not very helpful and instead asking them to try to solve the game by, for example working on a hypothetical like assuming a strong townread you two share is confirmed town and seeing how that affects the gamestate? things like that, are going to be way more productive ways to use the additional perspective than introducing unnecessary mindgames in to the equation

i imagine doing this as mafia is strictly either -EV or angleshooting but i can't prove that, it's mostly intuition

creating an inconsistency in your perspective that amounts to wilful ignorance isn't looking good to town unless it's minor enough to not matter to begin with. conversely if the goal of your hydra is that one person manages the role and night actions etc. without talking and the other is actually doing the playing/talking and knows nothing past that, then it probably is trending in the way of exploiting the rules, not necessarily for an advantage but absolutely is antithetical to the spirit of mafia to begin with
