Mensch oder Teufel

This film, much like the melodramas of Douglas Sirk, has far more going on than meets the eye. James Mason's character, after getting whacked out of Cortizone (a "Miracle Drug") indeed becomes hysterical and abusive. But he was made ill in the first place by the strain caused his intensely driven lifestyle, where he kept two jobs to finance his family's social and financial ascent.

What the viewer has to watch for is what his character says during his cortizone-induced delusions. His criticisms of his wife, kid, PTA and society in general are over-the-top, but essentially valid. It's a classic narrative device: by allowing a main character a way out of societal responsibility and place (In this case, being bombed on Cortizone), he is allowed to comment on and criticize American society directly without actually threatening the status quo. and in the case of 1950s America, that's a monolithic status quo to criticize.
