Is the sentence imposed on an appellant who was convicted of assault with intent to cause grievous bodily harm disproportionate?

Appellant argues that the instant offense was "non-violent" and therefore the sentence imposed is grossly disproportionate to the crime. What appellant fails to consider is that his crime could very well have caused a great deal of violence. In any event, "society's interest in deterring criminal conduct or punishing criminals is not always determined by the presence or absence of violence. [Citations.]" (People v. Cooper (1996) 43 Cal.App.4th 815, 826.)
