As to the passing allusion to God creating people for hell. That is not what the last revelation to mankind states, on the contrary, it says the creation of man is a natural consequence of God's attribute of mercy.
After detailing the divine law of retribution on a nation of rejectors and saying how Allah only destroys it after it has become utterly corrupt 11:116-7 the Quran says that God could prevent such doom by forcing mankind to be a single nation however people will keep differing regarding the Truth 11:118 and that is because, as a natural consequence of freedom of choice
92:4"Your striving is most surely (directed to) various (ends)".
Allah then states that those who are united owe it to His mercy, and all mankind has been created for that goal: to receive God's mercy
"and for this did He create them"
or as the Psalmist says in the HB
Ps144:9"The Lord is good to all, and His mercies are on all His works".
Mercy is a particular attribute of God, described as being "ordained" upon God's self 6:12,54. None of the other divine attributes have been described with this expression
"kataba ala nafsihi".
This statement is meant to emphasize that Allah is merciful but also that Allah made mercy a self imposed mandate upon himself. An interesting parallel can be made with a statement from the Tanakh
Psalms89:3"a world which manifests Your loving kindness, You did build".
Giving requires a receiver. So God created human beings to be the recipients of His bounty. He has brought mankind into existence and established a system of moral accountability it is therefore natural that He makes all necessary arrangements for a just retribution
41:2"A revelation from the Beneficent, the Merciful Allah".
Spiritual guidance is a natural consequence of this Mercy, despite most men being unworthy of it
43:5"shall We then turn away the reminder from you altogether because you are an extravagant people?"..
But since Allah's mercy is contingent on man's initial willingness and openess to guidance
13:11"surely Allah does not change the condition of a people until they change their own condition"
7:156" and My mercy encompasses all things; so I will ordain it (specially) for those who guard (against evil) and pay the poor-rate, and those who believe in Our communications"
all people do not receive it automatically as stated in 11:118.
11:119 is a confirmation of this law of causality, that men will by nature always differ regarding the truth 11:118, with perspectives and opinions as varied as the ever-changing patterns and meanders in the sky 51:7-9. They will always be prone to intellectual dissension because God has decreed that His guidance is not a compulsion 2:253, that people must choose their paths freely after guidance has been made clear to them 2:213,10:19,42:14,21 and consequently to that decree or "word" by Allah there will be people punished in Hell.
The HB contains the same concept when it states that
Prov16:4"The LORD has made all things for himself: yea, even the wicked for the day of evil".
God has thus pre-ordained that the wicked will be led to painful suffering, not that they were from the onset made wicked and consequently punished for it.
That is the meaning of "the word" and its "fulfillment" referred to in 11:119 and elsewhere
36:7,40:5-6,41:25,46:18,38:84-5"The truth then is and the truth do I speak: That I will most certainly fill hell with you and with those among them who follow you, all".
Allah will, according to His pre-ordained plan of causality in which He is in full control, fill hell with those creatures endowed with freewill who choose the misguidance of evil agents to His guidance
"and the Word of thy Lord shall be fulfilled: "I will fill Hell with jinns and men all together".
This law of causality to which humans and jinn have been subjected to and that may lead them to either punishement or reward obeys to a simple common sense logic referred to in many places such as in 32:15-20 or this verse from sura al aaraf which was quoted in the OP
7:179"And certainly We have created for hell many of the jinn and the men; they have hearts with which they do not understand, and they have eyes with which they do not see, and they have ears with which they do not hear; they are as cattle, nay, they are in worse errors; these are the heedless ones".
As stated in the second part of the verse, the category of people that have been made for hell are those who are heedless to their spiritual senses
, not that they have been made from birth with those characterisitics, meaning their final destination is nothing but a natural consequence of their spiritual condition
