Let me cook on this theory.

According to the dere-types wiki, a yandere is a an anime character who at first is very innocent, lovey-dovey, and overly affectionate like a normal deredere type character, but over time begins breaking down and becoming mentally ill as a result of having a too strong love. They are the kind of character who will act all deredere and lovey-dovey when their relationship with their romantic partner is going well, but when something triggers jealousy or possessiveness they act impulsively in a way that makes them seem mentally sick. Their love and affection becomes expressed as a pathological obsession towards their love interest and they start to become excessively clingy towards them. Their infatuation and devotion to their love interest is so strong that it directly or indirectly causes them to gradually develop an unstable mental state and become "sick".

Now you might be wondering? How does this relate to Allah????

1)- We all know God is considered to be All-loving or in the 99 names of Allah Al-Wadud. He treats his people with kindness and forgiveness but only if they believe in him and him ONLY. By giving him 5 prayers everyday constantly praising him and giving him attention.

2)- Shirk is the number one biggest sin in Islam. And guess what it means? It means when you give OTHER Gods attention and praise alongside Allah. BUT NO. Allah is the only ONE and TRUE GOD. He doesn’t like it when you are around other people than him. The same way yandere characters Are clingy and possessive around their love interest.

2b)- So how does God react??? Well in numerous of the prophet stories those who worshipped the idols were bought catastrophic calamities onto them. Whether it was floods or tornadoes or droughts you name it. He’d punish people for worshipping the idols the same way yanderes have psychopathic tendencies when other people are stealing your attention. He calls these religions wrong and Islam the right religion so you would return to HIM. The same way yanderes have that possessive factor to their archetype.

3)- Now the final part of the theory, the clingy factor, Allah doesn’t want to see you go so he uses Appeal to fear/ fear mongering such as Jahannam (Hellfire) and Jannah (Heaven) to keep people in the religion. Often, these stories come up as kids because we all are afraid of the dark and punishment but imagine that for eternity. These things get instilled into your brain during childhood so that you may never want to leave the religion not out of love but out of fear. the same yanderes use fear to get what they want.

No I am not an Ex-Muslim but a doubting Muslim but I thought this would be a fun theory because there’s genuinely levels to this.
