### Responsibility of Mao Zedong

Mao Zedong was responsible for many of the policies leading up to the events described. His emphasis on collective ownership and central planning led to significant suffering among his people. However, it is important to note that he did not directly order or execute specific violent acts such as those committed by the People’s Liberation Army. Instead, he often justified these actions through broader ideological justifications rather than direct orders.

### Historical Support

The historical evidence suggests a complex mix of both intentional policies and unintentional consequences under which Mao Zedong operated. He believed strongly in the necessity of these measures, but they ultimately resulted in widespread human suffering and death. This underscores the importance of considering context when attributing blame or responsibility.
