How to understand what Andolini in The Catcher in the Rye inspired Holden?

In my opinion, destruction is a lazy thing, whether it is destroying others or destroying yourself. Really mature and powerful people will not easily choose to destroy. "A real warrior dares to face a bleak life", even if the reality is unbearable, even if it is a desperate situation that can't even see a glimmer of light, a mature and powerful person has the courage to face it and then change it. There is probably a situation in the world where a person can still do things after death, but this situation is too rare. In most cases, heroic sacrifice is meaningless. This is like, a person who can't swim can't jump blindly to save people when he sees others fall into the water, but should live and continue to make contributions in his own field. This is a sign of maturity.
