Does the will of humankind superseded the will of God? It is God's will that all come to repentance.
And they will.
Everyone who has knees to bow and a tongue to speak, in heaven and on earth and under the earth (in the realm of the dead), will whole-heartedly, and without reservation, acknowledge that Jesus Christ is Lord. No one can say that “Jesus is Lord,” except by the Holy Spirit. If you declare with your mouth, “Jesus is Lord,” you will be saved. Christ died and returned to life so that he might be the Lord of both the dead and the living. (the reason for the bodily resurrection) Scriptural support below.
Philippians 2:10-11
that at the name of Jesus every knee should bow,
in heaven and on earth and under the earth,
11 and every tongue acknowledge that Jesus Christ is Lord,
to the glory of God the Father.
1 Corinthians 12:3
Therefore I want you to know that no one who is speaking by the Spirit of God says,
“Jesus be cursed,” and no one can say, “Jesus is Lord,” except by the Holy Spirit.
Romans 10:9
If you declare with your mouth, “Jesus is Lord,” and believe in your heart
that God raised him from the dead, you will be saved.
Romans 14:9
For this very reason, Christ died and returned to life so that
he might be the Lord of both the dead and the living.
Note on "acknowledge" in Philippians 2:11 from Strong's Concordance
S1843 eksomologéō (from 1537 /ek, "wholly out from," intensifying 3670 /homologéō, "say the same thing about") – properly, fully agree and to acknowledge that agreement openly (whole-heartedly); hence, to confess ("openly declare"), without reservation (no holding back).
Further reading: Isaiah 45:23; Romans 14:11; Revelation 15:4

While I'm uncertain about whether it's even possible for people to be forgiven in hell/hades, it may very well be, I do know for a fact some people will indeed blaspheme the Holy Spirit and refuse to repent until the end and they will be annihilated. The same is true for the devil himself - he doesn't want forgiveness and he never will.
Let's take the rich man and Lazarus for example:
"So he called to him, ‘Father Abraham, have pity on me and send Lazarus to dip the tip of his finger in water and cool my tongue, because I am in agony in this fire.’" - Luke 16:24
He felt sorry for himself, and still refused to care about Lazarus. In fact, he even commanded Abraham to send Lazarus to join him in that agonizing place, just so he could have a drop of water. He still did not care about Lazarus at all, and still felt justified for the life he lived.
Is it possible he eventually repented? Maybe. That would explain the purpose of the torment - a way of humbling him so he can reflect on what he did to Lazarus. I also know if it's possible for him to be redeemed, then he will be, and perhaps that torment will help do that. We can certainly hope so.
But it's also true some people - I don't know what percentage - will refuse repentance even in that place of torment until the day of judgement, where their soul will be thrown into the lake of fire, which is the second death.
If it is true people can be forgiven in hell/hades, then the reason Jesus didn't make it explicitly clear is because it might encourage people to not repent now, and may encourage them use the time they have here to live however they want to - ignoring God and not taking him seriously. After all, we know people are stupid enough to say "eh, I can just repent when I'm in hell then" - so this is purposefully concealed to prevent exactly that. We cannot claim to know either way for sure, and it is definitely true some people, maybe even only a few thousand out of the billions that have lived, will refuse to repent forever.
What I do know for sure though is we should treat every person as if they are on the path to hell and ultimately annihilation until they accept Jesus. There is no better guarantee than them getting into heaven than that. Indeed, hope for those who die in their sin that they may be given a chance in hell/hades, but certainly don't encourage anyone to die in it.
"For he says, “In the time of my favor I heard you, and in the day of salvation I helped you.” I tell you, now is the time of God’s favor, now is the day of salvation." - 2 Corinthians 6:2
"As has just been said: “Today, if you hear his voice, do not harden your hearts as you did in the rebellion.”" - Hebrews 3:15
It is God's desire that all come to repentance, but it's also God's will to give us a free will and not force us to repent. I do believe only a very rare few end up going to the second death, and they fully know where they're going, and willingly embrace it.
"They are wild waves of the sea, foaming up their shame; wandering stars, for whom blackest darkness has been reserved forever." - Jude 1:13
These are the hyper-religious false prophets. A very small percentage. Children of the devil, who know they are the devil's children. Evil is very real, and the highest form of evil is knowing fully what evil is and delighting in it, just like the demons and devil himself do. Like Catholic priest pedophiles.
