That's one avenue. Another avenue is to simply put an aggravating circumstance into the existing offence of aggravated assault, such that as a sentencing factor, if the harm that was caused was intentionally caused and not just recklessly caused, that could be an aggravating factor for the sentence which would be imposed to the existing offence of aggravated assault.
That's another way Parliament can show its denunciation for this type of conduct, not by creating a new offence, but by creating a specific aggravating sentencing factor for the existing offence of aggravated assault. You could create a new aggravating circumstance.
