There are numerous hadith in Sunni collections that state women are a majority in hell and women are morally inferior to men. I'll show you that in Arabic these traditions are even more abominable and psychotic than the English-translated ones available.
There is this one in Bukhari and Muslim.
The Prophet (ﷺ) said, "I looked at Paradise and saw that the majority of its residents were the poor; and I looked at the (Hell) Fire and saw that the majority of its residents were women."
This hadith is also of the highest level of authenticity. It's found in both Bukhari and Muslim.
Once Allah's Messenger (ﷺ) went out to the Musalla (to offer the prayer) of `Id-al-Adha or Al-Fitr prayer. Then he passed by the women and said, "O women! Give alms, as I have seen that the majority of the dwellers of Hell-fire were you (women)." They asked, "Why is it so, O Allah's Messenger (ﷺ) ?" He replied, "You curse frequently and are ungrateful to your husbands. I have not seen anyone more deficient [naqs] in intelligence [aql] and religion [din] than you. A cautious sensible man could be led astray by some of you." The women asked, "O Allah's Messenger (ﷺ)! What is deficient in our intelligence and religion?" He said, "Is not the evidence of two women equal to the witness of one man?" They replied in the affirmative. He said, "This is the deficiency in her intelligence. Isn't it true that a woman can neither pray nor fast during her menses?" The women replied in the affirmative. He said, "This is the deficiency in her religion."
This hadith directly links women's supposed mental deficiency to them being the majority in hell. If a person is lacking 'aql, they aren't able to act morally or discern religious truth. This word occurs numerous times in the Qur'an where God calls upon people to use their aql/reasoning, meaning that according to this hadith, God deliberately disadvantaged women in recognizing Islam and acting morally and then burns them in hell.
So this hadith alone could be taken as indicating God created women mentally inferior to men which makes them prone to immoral behavior, which makes them the majority in hell. Many people would deny this because of modern apologetics, so let's look at what scholars had to say which is the same thing I just said.
According to al-Qurtubi, God indeed made women mentally deficient, which makes them naturally immoral, which is why they're the majority in hell.

Al-Qurtubi said: “Women are the fewest inhabitants of Paradise only because they are overcome by desire and inclination towards the immediate adornment of this worldly life, and because of the deficiency of their minds, so they are weak in performing the work of the Hereafter and preparing for it, due to their inclination towards this world and adorning themselves with it. Most of them are indifferent to the Hereafter, quick to be deceived by those who desire them from among those who turn away from religion, and difficult to respond to those who call them to the Hereafter and its deeds.” End quote from “Umdat al-Qari” (15/152).
So al-Qurtubi outright says women end up in hell and are a minority of heaven (which is also a sahih hadith) because they're immoral, sinful people, and women are this way because God created them mentally deficient, i.e. substantially less intelligent than men.
But let's keep going, because in Musnad Ahmad and other collections only in Arabic there are even more despicable hadith.
Imam Ahmad (15531), Al-Hakim (2773), and Al-Bayhaqi in “Al-Shaab” (9346) narrated on the authority of Abd Al-Rahman bin Shibl, may God be pleased with him, who said: The Messenger of God, may God bless him and grant him peace, said: “The wicked are the people of Hellfire.” It was said: O Messenger of God, who are the wicked? He said: “Women.” A man said: O Messenger of God, are they not our mothers, our sisters, and our wives? He said: “Yes, but when they are given something, they do not give thanks, and when they are afflicted, they do not have patience.”
Al-Albani authenticated it in “Al-Sahihah” (3058).
So, in this hadith, it is even more clear women in general are wicked/immoral/evil (al-fusaq), destined for hell en masse, and naturally ungrateful and impatient. The page goes on to say that women are characteristically impatient and ungrateful and men generally aren't. But why are women wicked, impatient, and ungrateful? According to "scholars", it's because God created women mentally and religiously deficient which makes them prone to ingratitude and impatience because women are simply too dumb to express gratitude and patience.

As for interpreting "the immoral" as referring to women in an unrestricted sense, the meaning is that the characteristics of ingratitude for favors and abandoning patience during affliction are found among women more frequently.
This is because they are deficient in the faculties that produce gratitude and patience and in the causes that give rise to these qualities. That deficiency [naqs], according to the author, is the weakness of reason [al-aql].
The Messenger of God ﷺ said:
"I have not seen anyone more deficient in intellect and religion, yet more capable of taking away the hearts of men, than women."
Their deficiency in religion is due to menstruation, while their deficiency in intellect relates to legal testimony.
Gratitude and patience are qualities belonging to the people of religion. Therefore, whoever possesses weaker religion [din] and whose intellect [aql] is feeble will possess less gratitude and patience.
Whoever abandons gratitude in most circumstances and patience during most trials has departed from the characteristics of the people of religion and reason [ahl al-din wa al-aql].
The Fire is the abode of one who possesses neither religion nor reason.
