I was a supporter at the time, but soon left, very much on account of Madsen. I must admit that his later exploits in retrospect quite irrationally have tainted the entire project for me, and I'm not going back.
But is there any evidence to suggest his murderous behavior makes him a poor engineer?
I do agree that it is good he left the project long ago, though.
