Jeong Yul-seong is even more of a scumbag than Kim Won-bong

I didn't understand why certain political parties and the President kept praising Kim Won-bong,
but
Jeong Yul-seong is even more of an outright traitor than Kim Won-bong lol
I didn't even know who he was, but the more I learn, the more of a traitor he seems to be.
