The fact is, no matter who is right, we all agree that Manson didn't kill anyone, therefore, he should not have gone to prison. It is a very ugly thing when we say that people can go to jail because someone else said the only reason they killed somenoe was because they were told to do it. People need to be held accountable for their own action. At any point prior to those murders, the murderers could have said "ok, I'm not doing this", and I don't believe any psuedo-religious psychological counter otherwise. All that does is justify the murders.
