Making Sense of Pride in Islam vs Christianity's Original Sin

Assalamualaikum everyone! I was reflecting on Surah Sad, verse 75, where Allah asks Iblis about his refusal to prostrate to Adam, and it got me thinking: why does Islam emphasize 'original pride' coming from Shaytan, but not from Adam? The verse goes: Allah said, 'O Iblis, what prevented you from prostrating to that which I created with My hands? Were you arrogant, or were you among the arrogant?' Reading the surrounding verses (70-80) helps with context. So here's my confusion: if pride (kibr) is considered a root of disbelief, and it started with Iblis, does that mean we're accountable for his pride like some Christians think we're accountable for Adam's sin? Is pride the same as sin in Islam? After pondering, I realized: Islam teaches that arrogance was the first disobedience against Allah, stemming from Iblis's refusal to honor Adam out of pride, while the angels obeyed out of respect. Adam, as the first human, had his own test later, but the key point is we don't inherit Iblis's pride. Every soul is born with Fitrah-a pure nature inclined toward Allah-and we're responsible for our own choices, not Shaytan's actions. So unlike original sin, there's no inherited blame; it's about personal responsibility and avoiding arrogance ourselves. Hope that clears it up! JazakAllah khair for reading.
