You could just use the word "absolute." It works as a noun and an adjective.

so this type of word is an "absolute"?

Yeah, 'Absolution' isn't the word ya want for that sentiment.

Looking at my well-worn 'Synonym Finder' gives-

perfect, complete, entire, whole, comprehensive, total, ideal, consummate; full, plenary; uncut, solid, undivided, pure, clean, clear, faultless, flawless, unadulterated,,, ultimate, omnipotent, infallible.

For starters?

The word 'Absoluteness' is real, but reads/pronounces a bit awkwardly.

Good luck!

okay so those words can be known as an absolution? I thought so but I didn't think it was right or not.

It depends on the context.

For example: I am Never on time.

Genitive adverb?

Depending on the word or context, the nouns "absolute" or "superlative" can apply.

No problem. Hope that's what you needed, I know how these things can be tricky.
I was never good with parts of speech.

I experience that all too much...
