"Because it does help the mold. That's all it needs to do. It doesn't need to help us..."

If it kills the bacteria, it's helping both the mold and us. If it doesn't kill the bacteria, it's hurting both the mold and us. You're not making sense. The interests of humans and Pennicilium are the same in this case, so it the mold is adapting to its best interests, than it would adapt to ours as well.

Only if soil bacteria are the same strains as pathogenic bacteria. They aren't.

Besides, more dead people means more Ralston-Purina Mold Chow...

But the mold isn't exposed to the mutated bacteria, is it? They aren't wild type bacteria, they exist in humans. They aren't adapted well enough to live in the wild.

I suppose if you put penicillin and mutated bacteria in the same environment, you might be able to grow penicillin that adapted to the mutated bacteria, but evolution isn't predictable, and it usually isn't quick.
