After the liberation of Korea, members of the committee participated in North Korean politics as part of the guerrilla faction of Kim Il Sung.

[8] Pak was annoyed by the ballooning cult of personality of Kim Il-sung and how it neglected the experiences of people like him who had sacrificed a lot to the country during the liberation of Korea.

When Pak Kum-chol's wife Choe Chae-ryon died,[13] Kim To-man, who was the Director of the Propaganda and Agitation Department of the party, produced a work called An Act of Sincerity (일편단심) – described variously as either a film or a stage play – that portrayed her devotion to her husband.

[9] Pak was soon condemned by Choe Yong-gon, chairman of the Standing Committee of the Supreme People's Assembly, of proliferating "feudal, Confucian ideas".

[10] Pak was accused of not supporting the party's military line;[2] he openly ridiculed Kim Il Sung's slogan "one against a hundred" by concluding that a literal interpretation of it could not be true.

[10] At the fifteenth plenum of the fourth Central Committee of the WPK, on 4–8 April,[16] Kim had more than 100 faction members formally expelled from the party.
