Who am I? A puzzle in parts

Partial Answer

I wonder if the first paragraph is:

I am one of four brothers, we make a foundation

in some way we are native to every nation

if one is kind, the other is not

if one is a little the other is a lot

from what you give i will take

only 1 of my brothers will moreso break

Here's an answer that takes the current known information a little further, with some suggestions for what might need to be done next...

Stanza 1:

As @Dmihawk found (since confirmed by the OP), the answer to this stanza is:

I am one of four brothers, we make a foundation
in some way we are native to every nation
if one is kind, the other is not
if one is a little the other is a lot
from what you give i will take
only 1 of my brothers will moreso break

Stanza 2:

This stanza clues:

where to find the long lost party?
of those once high, yet became naughty
swallowed like a black like whole

wants your time, not your soul

sounds like the armor of your mouth
after water is burnt, it tis more south

Hint 2: Is there a place for a King of Sissies? And with his cat?

This is a further reference, cluing:

Stanza 3:

This stanza clues:

you yes you it is always true
but me yes me, it shall also be
then what is made when you are with me?
is that 1 plus 1 or is it 3?

The answer (a theory):

At this point we need to combine the words we have found using the arithmetic operations in between them - i.e. add the first to the second, then remove the letters of the third. Doing this gives us something like:

Still searching for a satisfying final answer, but I feel this has made decent progress, solving the 3 initial stanzas at the very least...
