Perfikot gathered the indigenous people on the island, and because she had previously hanged the plantation owner, these indigenous people, although not exactly grateful, still felt a certain sense of appreciation and were willing to believe what Perfikot said.
Therefore, when Perfikot gathered them to say that she wanted to demolish the plantations on the island and build something else, and employ them as workers, these indigenous people did not think that Perfikot intended to replace the plantation owner and continue to enslave them.
Though from a factual standpoint, being a worker in this era might not be much better than being a slave, and Perfikot indeed intended to make them work for her.
But to these indigenous people, Perfikot was much better than the plantation owner, so they chose to trust Perfikot.
And when it came to making a choice, these indigenous people were quite confused for some time.
