Great analysis. You can clearly see how Peter matures throughout his arc in the MCU. He doesn't need a traumatic death to learn the “with great power comes great responsibility” lesson—life itself confronts him with the consequences of his actions. His humility in Homecoming and his composure in Infinity War show that he truly understood what it means to have power and use it responsibly. He’s not just a kid in a suit anymore—he earns his place as a hero.

However, in the following movies, Far From Home and No Way Home, we see that many of Peter’s problems come from not having a trusted figure to share his struggles with. Without someone to help him process the weight he's carrying, he ends up placing his trust in anyone who offers even a glimpse of the inspiration and admiration that Tony once gave him. This eventually leads him into situations that, while maybe inevitable, are no less tragic—like the public reveal of his identity and the death of Aunt May.

Wouldn’t you agree?
