Anyone who’s played the game can tell you that the Medic is the FURTHEST thing from lawful and good.
“When ze patient woke up, his skeleton vas missing and ze doktor was never heard from again! Ahahaha! Anyway, zat’s how I lost my medical license!”

And Pyro isn't evil. He just wants to shower everyone with his happy rainbows that he doesn't know are fire.

There is nothing Lawful or Good about the medic.
