The theory that Qui-Gon is the only Jedi Anakin ever saw as a “truly good man” is a nice theory, but ultimately just that - a theory. There’s evidence to support it, but at the end of the day nothing like that is ever clearly (or even subtly) communicated in the films.

The entire character of Qui-Gon is utterly wasted since nothing results from his death. If Obi-Wan was reckless in TPM and it caused him to become more stoic, then that would be a character thing. If he was a figure that Anakin looked up to and Obi-Wan always failed to match him as a teacher then that would be a character thing. But for any of that to work you have to actually write characters.
