I'm glad you worded it that way - it took me 3 tries to find Waldo
Maybe good "tries" to help others, but "stupid good" is often explicitly at the expense of (the fun of) others (and one's self).
So… good is evil?
IME, most gaming groups are terrible at communication. They act with hubris and unfounded assumptions, and make things that are terrible without thinking about it.
Evil, at least, is actually trying to do good - is actually trying to make something of verifiable value.
*And* evil is much more likely to result in productive communication, to move towards collaborative gaming: I'm trying to defend *my* fun, but, to do that, I need (or would benefit from) your help.
Good doesn't have such fail-safes, such inherent modes of improvement built in.
That… is complicated. Such differences… need not be incompatibilities; they can instead result in a full-course meal. Whether that's better than just eating appetizers or just eating desert is a matter of opinion; I, personally, can appreciate both.
I'm not sure that your explanation matches "how you have fun".
And, still playing evil's advocate, note how personal growth / improvement is inherent in Evil (getting kicked out isn't conducive to having fun), whereas good has no such incentives built in (and I've seen lots of idiotic good, in games and other areas of life, making things worse in the name of misperception, that keep harming things in part because they not only lack such incentives to improve, but because "belief that they've done good" actively incentives them to keep their blinders on).
