Even if all they amount to is cannon fodder, that free's up the more able bodied individuals that are more capable from needing to do the same job. Instead you can send them to do what needs doing directly.
Even Satsuki-sama came to agree with this during the war. The slackers and self proclaimed underachievers who would have been cast out for failing to build the sheer resolve to overcome being a no-star are still useful even if not inspired by her will. To the point that in the final push it was those who failed who were the first to receive the last of the Goku uniforms.
It's just a matter of what will it take to get them to be useful. So long as they rise above their shackles as mere pigs the path they took doesn't matter in the slightest.
