When I see Ko Young-wook attacking other celebrities on social media from time to time

‌It gives me a bit of a certain impression.
Looking at the targets of his attacks, it feels like he's upset because they cut ties with him or didn't help him out after his own scandal broke?
Of course, he probably uses social media because he wants to maintain his presence, and being cut off is a consequence of his own actions, but
when I see him attacking people using strange logic—mostly people he used to work with and get along with when he was successful on variety shows in the past—
it feels like he's actually resentful that those targets, who have mostly been blacklisted and are struggling themselves, have different attitudes now compared to the past, and he finds that hypocritical.
In fact, when he attacks certain celebrities like Lee Sang-min or Yoo Jae-suk, he uses wording that accuses them of being hypocritical.
