Let's see,

Matty doesn't actually have many choices does he ? It's sort of;
"Hey, Big Boy, Do what I want or I'll use my social status to make your life unpleasant".
Followed by;
"What the F***? Who the F*** are YOU? Get up and die like a man!"

Lord Donald's Wife abuses power but if she's guilty of adultery then so is Matty.

Lady Donald's Husband over-reacts a bit granted but I'm not sure he'd want his private inadequacies dragged though the courts.

The Page. Well he's only doing his job you know. I mean a sworn vassal and all that. Can't go letting the side down can he?

All in all I think the villain is society for giving people holidays. It wouldn't have happened if Matty had been bringing the yearlings home with the boss instead of gallivanting about and hanging out round churches.
