No. A person may have a very gruff, rough look but be a very sweet, kind helpful person. Or on the other hand, they could be like a news story I heard. A little old lady, she looked like the nice, sweet grandma that bakes great cookies...she was convicted of embezzlement. So, yeah, not a good idea to judge people by their looks. Hope this helps!
