The mere presence of a person when a crime is committed will not render him an accessory, although he may consent to the perpetration, unless he in some manner aided, abetted, assisted or encouraged, in its commission.45

Where one is charged with aiding and abetting another in the commission of a felony and is found guilty of a misdemeanor included in the felony charged, he is principal as to the offense of which he was convicted, because there are no degrees of guilt in misdemeanors.46
