I thought he really looked odd, but yes, he was evil looking. “Old Coot Biden”, - that name really fits.
Notice that he looks years older than Trump. As one Grandmother would say, “that's the meanness coming out “.
He displays pure malevolence when he yells and whispers like he does. His face even contorts to look evil.
I have no doubt he is a bad person but sometimes I think his malevolent behavior, including the clenched fists, make him think he looks strong and tough in his addled half a brain.
