Humans are brainwashed into thinking it's "Human nature" to be greedy and self-centered, so when someone comes offering help those stuck in this condition can't help but think "What's the catch?"

And the clearer it is that the person has good intent, the more dangerous the catch must be.

"but you're gonna take my private property !"

the fear for good, is the fear for change or admitting they where wrong. it is pride, as well as lazyness, combined with stupidity and weakness. because weakness is not how strong one seems(or lack there of) but weakness, is how little a person would be their real self, as well as how much they assume that in order to be strong they need to supress others so they are in a worse state than them. supressing people is a sign of the weak, because they are blinded and can only destroy.
