Arising out of that you would ask yourself, and you would need to answer - and again upon the basis of proof beyond reasonable doubt - these questions. Firstly, did the two accused people form a common intention to prosecute an unlawful purpose in conjunction with one another.
You can form such an intention, as I say, just the same way as we have been already speaking of, without prior discussion. It does not need to be a formal agreement. They do not need to have sat down in the pub and talked about, 'What unlawful purpose will we perform upon Locke?' You need only to find that there was an identicality of their minds in relation to a particular unlawful purpose.
Let us describe it. It is a matter entirely for your judgment. Let us describe it for the purposes of discussion as a question: did they form a common intention to bash, to beat up, to assault, to assault perhaps in a particular type of way - but to assault and perhaps to assault with a particular type of severity. But was that their common intention formed at some stage, perhaps if not initially then ultimately, but necessarily before the death occurred?
If you answer that question affirmatively, you then go to the nature of the killing and you say, 'What was the nature of the killing which resulted from the pursuit of that common purpose?' You see, it is in the prosecution of that purpose that an offence is committed. You looked at a killing and you say, 'Was that a killing which was committed in the prosecution of that purpose? What was its nature? Was it a wilful murder; was it a murder; was it a manslaughter?' having regard to all the discussion that we have had about that.
Then you go on to ask yourself the question, 'Well, was that killing a probable consequence - ' that is a killing, for example, done with an intent to cause grievous bodily harm or a killing done with an intent to kill or a killing done, as I say, without you being satisfied that it was accompanied by either of those intents, but was that killing, whatever you find it to be, one which was of such a nature that its commission was a probable consequence of the prosecution of such purpose?
