[Ant Man] Why is Cross so focused on weaponizing his "Cross Particles"?

Cross already said they perfected shrinking non-organic matter, which begs the question: why not just cash the infinite money check of being able to resize matter at will? Industrial uses for resized machinery and electronics alone would be akin to inventing electricity and having the controlling interest in that technology would make him an over night trillionaire.

Mostly because of his overblown ego. Cross was the “got to be the smartest” type. His mentor had developed a safe and effective way to shrink organic matter years prior, and never let Cross in on how. So Cross was not only going to rediscover the method, he was going to make a mint doing it. 

People even told him he should stop while he was ahead and he just gave them the typical “I’m gonna go all the way” egotistical villain response.
