What is with Thunderclan

Hi there, today I thought about this: why doesn't Thunderclan mind it`s own beeswax. I`m not trying to be rude to Erin Hunter, but that is what I find interesting. Like, when ever a cat or a different clan needs help they think it`s their business. I think that they act goody goody. One example is when Windclan needed help they just thought that they should go out and help them. Even though in the end it was all good that still does'nt mean that they should keep doing it in the first place. Even though the cats do not always want their help, they still do it no matter what.
