The Broken Jug: Why Adam's Appearance is Important

When reading/watching The Broken Jug, I felt sorry for Adam. He was an ugly, bald club-footed bachelor. His appearance is probably a significant part of the reason he wasn't able to find a wife. He tries to make light of the situation by writing a list of the perks of being a bachelor.
"That's the advantage of bachelorhood. What others, in restricted circumstances, are forced by need to share with wife and children, we bachelors enjoy to the full at our leisure, and share it with a friend."
It is obvious to me that he does not enjoy being single. It is probably, at least in part, because of this that he forces himself on Eve, breaks the jug, and then lies about it.
But in this play, the references to Judge Adam's appearance aren't cruel. That is, none of the humour in the play is derived from Adam's unfortunate appearance. Rather, his ugly exterior is just an extension of his ugly personality.
I think this is an important distinction. If the other characters made fun of Adam for being hideous, the villain could easily be turned into Eve. Adam wouldn't want to tell the truth about being at Eve's because the townspeople would laugh at his failed attempt at romance.
When his appearance is just part of his bad personality, it helps to vilify him. He becomes the exact opposite of sweet, innocent Eve. This added dimension of the characters really drew me into the play and also into a position to appreciate the hilarity of the situation further.
His monstrous facade, which is a device to further his malicious character, is also the main reason I feel pity for him in the end. Despite lying about tripping in the beginning of the play, he probably is exceptionally clumsy with club foot. He probably has a certain level of self esteem issues as well, and these could be the foundation for his poor actions. I am able to relate to Adam, and thus I see his humanity. He's not perfect. Like his namesake, he messed up, but he's only human. We can forgive him.
It is because of all of these reasons that the way Adam looks is important.
