Satan has done a lot, but there's no way for Satan to secretly finish everything for the Solar System Company, nor is it necessary.
The Solar System Company now has its own employees. If Satan solves all threats, what's the point of paying the mercenaries of the Solar System Company high salaries?
Attacking the Three-leaf Jungle, this competitor, is just a side task. The situation is now open, and it's best for the Solar System Company to stand out from many competitors using its own strength.
If Satan were to secretly eliminate all competitors... that would be great, but Satan doesn't have such strong power and can't get this done without any casualties.
