Isn’t Kai Shek one of the most important founders of Taiwan? Sure, he had his issues (for example, ordering the deaths of a couple folks now and again), but you cannot have modern Taiwan without him. Just like how Mao is an integral part of the shape the modern PRC took.
The February 28 incident (also called the February 28 massacre, the 228 incident, or the 228 massacre) was an anti-government uprising in Taiwan in 1947 that was violently suppressed by the Kuomintang–led nationalist government of the Republic of China (ROC). Directed by provincial governor Chen Yi and president Chiang Kai-shek, thousands of civilians were killed beginning on February 28. The incident is considered to be one of the most important events in Taiwan's modern history and was a critical impetus for the Taiwan independence movement.
Bad take. You couldn't have pretty much any modern country without their previous problematic leader. You can learn just about them in history class and not honour them though statues.
