Sure, the Superman of the Golden Age faced stret level crime. He also faced munitions dealers who were provoking wars.
The GA Superman didn't have the constant self doubt the current one does. He did what was right and did it, even he was hunted by the police.
That's a different topic. And I wouldn't mind seeing the contemporary Superman going after munitions dealers either.
The self-doubt seems to be on its way out, thankfully.
