James Lockyer and Eva Taché-Green, for appellant.
Andreea Baiasu, for respondent.
The judgment of the court was delivered by
 WATT J.A.: — Several men gathered outside a restaurant in
a mall, including Mao Kim, Vandin Svay and the appellant,
 The appellant asked, “Who is Mao?”. Vandin Svay spread
his arms. The appellant backed up. A fight began with a number
of men on both sides.
 Vandin Svay and Mao Kim were stabbed. Vandin Svay died.
Mao Kim survived but was seriously injured.
 Police investigated. The appellant was charged with second
degree murder and attempted murder. Four others were charged
jointly with manslaughter and aggravated assault.
 At the end of a lengthy joint trial, the jury found the appellant guilty of second degree murder and attempted murder. The
other four men were found not guilty of both counts with which
they were charged.
 The appellant appeals. Focusing on the conviction of second
degree murder, he says that the judge’s charge to the jury contains several errors, some of omission, others of commission,
which singly, or at the very least in combination, require that the
convictions be set aside and a new trial ordered.
 As will become apparent from the reasons that follow, I do
not agree with the appellant and would dismiss the appeal.
The Background Facts
 In general terms, the controverted issue at trial was the nature and extent of the appellant’s culpability. As the principal, did
his conduct constitute second degree murder and attempted murder, as the Crown contended, or manslaughter and aggravated assault, as the appellant argued?
 The Century Palace Restaurant is located in the Century
Plaza Mall. The restaurant does not have a video surveillance system but several cameras are installed at different locations around
the mall. Some blind spots exist but much of the activity that
takes place in the corridors is captured by the cameras.
 The doors of the Century Palace Restaurant open to one of
the corridors in the mall. Two surveillance cameras record activity in the immediate vicinity of these doors.
 One Saturday evening in mid-October a few years ago, several people attended a party at the restaurant. Admission required
