Hades failed to meet all the conditions that would result in his victory. You must meet the required conditions in order for something to occur, mustn't you? Certain things must happen before we get the result we want; or any result for that matter! For instance, to be born, to breathe and to talk, certain conditions must be met. Breath requires air and lungs. Birth requires a sperm and an egg. Talking requires a brain, a mouth, teeth, a tongue and some type of language. Everything relies on the necessary conditions. Right? No. Love is unconditional. Love requires no conditions. You don't need eyes to see or ears to hear. You don't need skin to feel or blood in order to bleed. These things happen unconditionally...without conditions. Certain criteria need not be met for the sun to shine or the wind to blow. Leaves dance within the treetops without wind. They dance unconditionally... without needing or depending on anything. You are without conditions.
"Unconditional" means just that; without conditions. Everything that is "happening" is doing so unconditionally. There are no conditions or conditioning. Nothing occurs "because..." or "in order to..." or "as a result of...".
Everything is a cause, without an effect. there are not conditions to meet to reach "heaven". There are no conditions to meet to reach "hell". So...where does that leave you?
