What is a good even though thesis for Sir Francis Drake?

A compelling thesis for Sir Francis Drake could argue that, even though he is celebrated as a national hero for his role in defeating the Spanish Armada and circumnavigating the globe, his legacy is complicated by his involvement in piracy and the impact of his actions on indigenous populations. This duality highlights the tension between his contributions to British naval power and the moral implications of his exploits. Ultimately, Drake's life exemplifies the complexities of heroism in the context of colonialism and maritime conflict.
