I would love to see you pull that shit to any other major alliance, when you recover from getting rolled.
Also you keep saying this isn't real life. Although it is true, as long as players are "human", gameplay will reflect the real-life interactions. So just like when someone in your family gets attacked and you beat the shit out of that punk, when a member of your alliance gets attacked, he goes down. Simple as that.
Many people also kept explaining the benefits of rolling a raider to death to the reputation of the alliance but as far as i see, you are just ignoring them. Therefore, I conclude that you are just trolling the whole orbis by saying:
People play this game this way. You are closing your eyes to everyone that explains how wrong are you and you keep ignoring and ridiculously saying "everyone is stupid blah blah". If you can adapt it, play it. If not beat it, kid.
