I am right, GBH with intent also carries a life tarrif and a conviction is more likely to carry a harsh penalty than manslaughter, purely because of the intent. The survival of the victim is not necessary for GBH. As I say, there was an attempt to show that there may have been other causes for his death and if accepted by the jury would have resulted in an acquittal for manslaughter, but a charge of GBH would still have stood up.
