It was bad, though it's often wrongly said to be bad for superhero comics.
There's nothing the Code prevented that superhero comics need to do, and after the Code was revised in 1970 or so, it was probably more permissive than the actual publishers (hence, Jim Shooter decided to ban the use of mild profanity like "Hell" and "Damn" but the Code had allowed those for years already).
It's a bit like the Hollywood Production Code. Most of the rules (crime must always be punished, ditto sex out of wedlock) weren't a problem for the type of escapist family-friendly movies that Hollywood primarily made. They were a terrible drag on any movie that tried to be realistic, because the Code forced films to lie about what the world is like.
Same with comics. Superheroes are frankly escapist entertainment for children, evil would always get punished with or without the Code. But you can't make "serious" or even semi-realistic comics that way.
