Regarding the "if he hadn't struggled, he would have lived" comment, there's something I don't understand. In an asphyxiation situation, death doesn't happen immediately. First, the body struggles, then unconsciousness comes, then a while after that, death.
If the death was a result of him struggling, why did he die after becoming unconscious? Unless, of course, the suggestion is that his unconscious body continued struggling? That doesn't make sense.
