Back on the Avatar Planet, Duanmu Huai once said that when two unfamiliar animals meet in nature, the first thing to do is to show their deterrence to one another, making each other understand their prowess, which then forms a basis for communication. It's not like those foolish scientists who stupidly show that they mean no harm...
It's the same for animals and humans; you must first show that you're not easy to mess with, only then can everyone sit down together!
The same goes for the Outer Gods!
Duanmu Huai didn't expect to sit down and have a nice talk with Yog Sothoth, so he decided to use reason to persuade—by beating him up!
