I believe the actions are sane because there is some level of reasoning behind them at all. To say that they are insane is, by definition, suggesting that the cause behind them is mental illness. Believing it's ok to kill someone is insane. Thinking oneself to be godlike is insane. I don't think we should use the same rhetoric for someone asking a person to delete their characters in a video game. I can agree though, the behaviour is definitely harmful for the community. It should be condemned, I just think that everyone should be given the common decency of not being called insane unless they have an actual mental illness.
