Views about the case in South Africa are very mixed.
Every South African lawyer that I've spoken to thinks (as I do) that the trial judge got the law disastrously wrong. If Oscar intended to kill whoever was behind the bathroom door (or was reconciled to that result whether or not he intended it) then the only question remaining was whether he could bring himself within the ambit of self-defence. The trial judge (correctly) held that he had failed to meet the (very strict) terms of the defence (which would have resulted in a verdict of Not Guilty), but went on to hold that his evidence on this issue justified a finding that he might not have intended to kill but rather was negligent -- thereby rendering the crime not murder but culpable homicide. This is arrant nonsense and the Appeal Court judges say so (in clear but commendably restrained terms). The best analysis that I've read so far is this piece by Findlay Stark:

Apart from lawyers, most of my South African male friends and acquaintances think that the original verdict was wrong and that he ought to have been convicted of murder. I should say that many of these friends and acquaintances are (or were) police officers so perhaps that's only to be expected. Most of my female friends and acquaintances have more sympathy for Oscar. But that is not usually because they swallow the intruder story, but because they regard Reeva Steenkamp as having been "no better than she should be" and as having driven poor, vulnerable Oscar over the edge with her rondlopery (a lovely Afrikaans expression for being free with one's favours).
