Realistically, you can say the same of all the Big 3 being generous and kindly towards other players. Of the 3, Roger is likely the most reserved, but Rafa has an academy which seems to have a pretty open-door policy to players, and he is known to mentor. As to philanthropy, they are all famous in their foundations, but giving away money is easier when you tax-shelter outside of your home country, isn't it?
In terms of making a decision and sticking to it, Novak didn't stick to his guns against Oz and their vaccination mandate. He looked for the work-around, and thought he had it. Sure, he's good at languages, which is a gift, but he's not necessarily good at the empathy of reading cultures, which is the more important part about learning languages. Not just having a good ear and memorizing a few phrases. He certainly got the Australians all wrong when he crowed about his (supposed) exemption into Australia. (And let's face it, he doesn't speak 11 languages. His English is excellent, his Italian is pretty good, and his French is more than passing, but not by much. How much Chinese does he speak, really?)
As to being the most "honest and thoughtful," well, surely that's a fan's perspective. Sometimes he's honest to a fault, such as exposing his vaccination opinions before he needed to, then wondering why he kept getting asked about it. Unforced error. But "thoughtful?" Go back to the tape on when he hit that lines person in the throat, and it was all about HIS USOpen. And how "at least she didn't need to go to the hospital." Nice. Yes, he thinks a lot about his New Age concepts, but some of them are pretty weird and misguided. (IMO.) Having a thought in your head doesn't actually make you "thoughtful." Flinging his racquet around in anger is not the action of a thoughtful person. He's an egotist who likes to "think" of himself as a nice person.
