[@CrazyShadowy] Well not everyone (characters and real people) can be as magnificent as you, good sir. I disagree, however, that "the assumption thing and judging everyone is a bit BS". How people dress, how they carry themselves, the look in their eyes... it can tell a great deal about a person if you know what you're doing. And the truth is, everyone in the world judges others in their head. Even you choosing NOT to judge someone based purely off of the previous traits I mentioned is a form of judgement. You believe that person needs more analyses before you get a comprehensive understanding of who they are. If someone confides a dark secret in you, and you choose to accept them anyways, that is still passing judgement. You would be passing the judgement that whatever they've done/are doing/etc, they still deserve to be treated with fairness. 

Judgments don't always have to be associated with negativity. 

In Miora's case specifically, the way she analyzes these other people fits her personality well. She is, as stated in the character app "brash", "blunt", and "generally offensive". So unless that's all a projection, the same behavior exhibited in her speech would also be exhibited in her thoughts.   

EDIT: To avoid another, uh, "incident", I want to point out that the first sentence of this post is entirely genuine. It's great for you and the people you affect that you try not to judge others negatively.
