Who were the English christians who felt that the church of England was too corrupt to be reformed and that completely leaving it was the only righteous option

The English Christians who felt that the Church of England was too corrupt to be reformed and that completely leaving it was the only righteous option were known as Separatists or Puritans. These individuals believed in a simpler, more pure form of worship, and they sought to separate themselves from the perceived corruption and worldly influences within the Church of England. In the early 17th century, some Separatists chose to leave England altogether and migrated to North America, where they established colonies such as Plymouth in what is now Massachusetts.
