Kim Dokja despises mainly three things/peopleโKim Namwoon, the constellations, and his mother.
He hates Kim Namwoon for his hypocrisy, for the gall he has to fight alongside Yoo Jonghyuk as his companion despite his evil and unworthy nature. He hates the constellations for watching him and his companions' suffering from afar for their own entertainment. Lastly, he hates his mother because she imposed her own self-sacrifice on him by taking his role as a 'murderer' and deceiving him. She assumed that was what's best for him without even hearing out what he had to say, abandoning him as a result.
It all sounds familiar, doesn't it?
You then realize he despises them because they remind him of himself. Because there's no one Kim Dokja loathes more than his very own being.
