If Allah sent the prophet as a bad looking man and he did not receive positive reinforcement and reciprocal affection because of his looks would that not have helped deviate him into being a non-believer from birth? The prophet's character was determined by his social status which is determined by looks.
Being grateful in Islam rewards you.
“If you are grateful, I will surely increase you [in favor].” (Qur’an 14:7)
“Repel [evil] by that which is better; and thereupon the one whom between you and him is enmity [will become] as though he was a devoted friend.” (Qur’an 41:34)
What does it mean to be grateful? It is to feel thankful of a benefit you receive, being a sub5 is not a benefit and it leads to social torment. Chad is granted something to be thankful about, his genetics allow him a greater capability to enact grateful favors. A sub5 experiences social scorn and genetic discrimination. A sub5 is socially stunted and being grateful is a social action, a sub5 is genetically not social. Your capacity to receive favors and be grateful for them is granted to you at birth, therefore, you are born into kindness and Allah's blessings onto you were determined at birth.
Qur'an 41:34 expects reciprocity for repelling evil with that which is better. What does it mean to be better if you aren't granted the social ability to be recognized for your actions? If you are by default discriminated against, then to be better will not receive you reciprocity.
“O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted.” (Qur’an 49:13)
“Whoever does righteousness, whether male or female, while being a believer—those will enter Paradise and will not be wronged, [even as much as] the speck on a date seed.” (Qur’an 4:124)
If Allah wills us not to discriminate for things that aren't controlled for, then your subconscious actions should also not be judged by Allah. How can you have the capacity for good when you can only experience evil? Nobility is the act of good and only those who experience good (who are genetically blessed) have the biggest capacity for reciprocal good. It is easy to help someone when you are well off.
“Whoever wills—let him believe; and whoever wills—let him disbelieve.” (Qur’an 18:29)
“Each soul is held in pledge for what it has earned.” (Qur’an 74:38)
“Indeed, those who disbelieve and die while they are disbelievers—upon them is the curse of God.” (Qur’an 2:161)
“Indeed, Allah does not wrong the people at all, but it is the people who are wronging themselves.” (Qur’an 10:44)
If the act and amount of good you show to people lies on your role in the social hierarchy and good rewards you, why should an incel (one who does not experience good) become a believer in Islam instead of cursing Allah for his torment? Allah has cursed you by birthing you. Should you be thankful to Allah as Chad is given the same fate in Jannah as you after suffering humiliation by Chad? Are incels simply born to suffer?
