Hades was the 'slave' of Yami for a long, long time. Never was he respected or appreciated. Undead didn't really have the concept of honor and comraderie.
Whenever they did show emotions, it was to deal with the living. A mask on their skinless face.
As a fellow Undead, Yami treated him without any filters. And she never thought of giving him even a mini-sliver of death, despite it being very helpful for his ascension.
With his talent, Hades could've also reached high rank 2 long ago if he was bestowed the mini-sliver.
He even requested it multiple times. In the end, he begged her for temporary usage. She still denied it.
'You are not qualified, slave. The sliver of death is wielded by the ruler of undead. You are no king.'
And yet—
"Why?!"
The sky turned red, as it's the bleeding Hades' heart.
The flames in Hades' eyes flared up, turning pitch black, as they stared at Varian with vengence bottled up for millions of years.
