Why did the Catholic Church repress those who questioned its ideals?

The Catholic Church repressed those who questioned its ideals to maintain doctrinal unity and authority, fearing that dissent could lead to societal instability and undermine its spiritual and political power. This repression was often justified by the belief that heretical ideas threatened the salvation of souls and the integrity of the Church. By silencing dissenting voices, the Church aimed to protect its teachings and uphold its influence in a tumultuous historical context.
