So the copyright law only applies if we agree with the organistion the copyright belongs to?
It's a question of ethics. Nobody has argued about the legal position.
If the WT obtained the copyright to COC it would be the moral equivalent of book-burning by a totalitarian regime. Spreading the information would be a moral good regardless of the law.
That is not the current position with COC. The copyright holder is in the process of making the information widely available and it is ethical to support that.
Is murder ok if the murdee (new word!) is a bit of a twat?
No. Complete red herring.
We live in a society where we agree to give the state a monopoly in violence. It works better than allowing everybody to murder people they find annoying.
