Right, but there have always been at least a few smart Super Mutants, even if they weren't nice. Lou Tenant from Fallout 1 instantly comes to mind. The guy had a few screws loose, but he sure as hell wasn't a retard.
There's also Marcus, who was very smart and nice, but still loved to smash things and rip people apart. There's also Fawkes, Mean Sonofabitch, Gramma Lily, etc.
