Alright fantomas you need to take a breath and realise that differing people have differing opinions.
You were killed because you were widely town read and a very active participant that wasn't scum
The whole point of scum is to control the game and all narratives, its not easy to do that when you have active players trying to solve.
You weren't protected because the doctor obviously thought someone else was more town than you, or more likely to be shot. It doesn't really matter, you absolutely should not rely on a doctor protecting you because you think you're being town as fuck.
Scum were fairly bold in going for you early but at that point they were not under heavy suspicion and were also the most active players, the numbers were in their favour.
Every game is different, and priority is adjusted for people who die very early. Enough people in this community are barely trying as town, the solution isn't to get upset and decide I'm never trying again, that just angers other players who like to try and solve the game but have these unnecessary hurdles in the way.
You're not unique. Grizzly usually dies N2 when not scum and is a good shout of dying again this game on N2.
If you honestly think you want to live long and have to not invest effort to do so, then you're just as problematic as players who sign up intentionally to goof shit.
Don't play if you're not willing to fully commit to your role, regardless of alignment.
