Where a person instigates another to commit a crime, and a crime is actually committed after such instigation by the person instigated, it is immaterial whether the crime actually committed is the same as that instigated or not, or whether the crime is committed in the manner suggested or not; provided in either case that the facts constituting the crime actually committed are a probable consequence of carrying out the instigation. In any such case the instigator is deemed to have himself committed the crime actually committed.
