How to evaluate Tokugawa Shigeru's role in The Silver Soul?

An ambitious general wanted to change Edo and Japan, but he never succeeded in his life.

In fact, I wanted to say that he was unlucky, but among a group of people who wanted to kill him in the shogunate, there were partners who tried their best to protect his life, such as the True Selection Group and the Imperial Court Fanzhong. I thought it was young people's luck. I really didn't cry in the episode where the teenager died, especially when I thought of his sentence "General passed down from generation to generation-". I want to strangle the gorilla ... now I can only pray that this is not the real ending of the teenager, despite history.
