So, killing people by mass vote is a form of group decision making?
Wouldn't not killing by discussion also be such?
How do you know murder or theft is what would happen (what is)?
If people decide to kill then someone dies. I'm not really sure what you are asking. I dont know what would happen. Again, I am not talking about what should happen.
Speculating? Sure. I am not saying there literally is a group of 100 deciding to kill someone. You asked of a group who decided to kill could kill. I am saying yes.
