Batman: Arkham city

Execute Humer, although he might just not know how to play Mafia, which is why he writes like that.

Humer. They are going to execute you, and being killed contradicts the goal of the game. If you are killed, you lose! Even if the side you are playing for wins, it won't matter as much to you. So, to avoid being executed, you need to argue why you are not Mafia, even if you actually are. You have to convince us that you are innocent, and this

2. I'm not lucky with "cool" roles.
3. Mafia can't have a cute avatar.
4. I'm not Mafia.

is not an argument at all; it's just chatter. Or do you think you're joking, and we're not executing you as a joke either?)

1. If I were Mafia, I would be more active. (not an argument, but still)

This is also not an argument, or rather, it's an argument in the opposite direction. Because usually, Mafia behaves passively – and rightly so, why would they help the town find themselves? There are active Mafia players, but you need to know how to play that way, because the task of such a Mafia player is to convince the town that someone from the innocent side is Mafia, so they get executed. But you don't look like a skilled player at all.
So, your life is hanging by a thread, you've almost lost, and you'll be executed in thirty minutes. You can reveal your role and tell us what you did each night. If it's convincing, we'll believe you and won't kill you, and we might even protect you as an innocent player with a useful special ability. Otherwise, everyone will just think you're Mafia, and they'll execute you. As a result, you'll lose, and you won't be of any use to your team, whether you're Mafia or a town member.
