Show me whose the worst bottom in BL?

I’m not talking about whiny, pathetic, insufferable, and no self worth bottoms (like dr Dan from jinx).
I’m talking about the ruins that are ABSOLUTE shit towards the tops.
A perfect fucking example is chunwoo from Lucky paradise, who mentally abused the top (ho in) and cheated on him with his ex (that he raped).
We already done the worst tops in BL, now I want the worst bottoms
