Finality - Tradução em português

Hey Guys, well I'd like to know what does "finality" means. I was searching for a word that has to do with "finalidade" that in portuguese means "aim, purpose", and I found out the word "finality", but I realized in the dictionary definitions that "Finality" doesn't mean "aim, purpose" at all, and actually I didn't understand the meaning of this word quite well. According to the dictionaries It is "the quality of being final", like "the finality of death". Could it be translated for "fatalidade" so?

What do you english experts think? Could you guys cast a l ight on thisd matter for me? I really appreciated it.

See you!
