Drudgeworth

Drudgeworth is a prisoner in Castle Britannia.

When finding him in a cell in the basement in Ultima V, Drudgeworth was claiming that he hadn't killed "her" (whose identity got never revealed), claiming that he knew where something was hidden and that Chuckles was responsible for his imprisonment.

It was clear that he'd lost his mind.
