Xi Jinping为国家统一拼命，or for his own evil power ambition拼命?

On Feb 2018, Xi Jinping removed the two term limit of presidency. Some people have claimed that Xi did it since he wants to unfiy Taiwan. So Xi Jinping is a great person and a great leader, and we all should listen to him.

An interesting qusetion is: if Xi Jinping is another leader like Deng, Jiang, and Hu and he goes home in 2023, does that mean that China will not unify with Taiwan? Is Xi Jinping is the only person who is able to unify China? Will China be dissolved without Xi Jinping?

Should Xi Jinping be the only hope of China, I would support him. In any sense, I love my motherland China.

However, my judgement is that Xi Jinping is an evil person. He did everything for his own power hunger stomach. Without him, China will be much better. Hence, I am totally against him.
