Aggressive doesn't necessarily mean physical aggression toward others. It can mean that the person is verbally aggressive or confrontational because of impaired communication skill, sensory distress, or anxiety. It can also mean the person is aggressive toward themselves (meltdowns, self-injurious behaviour).
The definition you are looking at doesn't suggest a higher risk of criminality or physical aggression.
I took medication for my "autistic aggression" and it had nothing to do with hurting other people physically.
