"If the westerners are "most rational people""
They are not. They are empiricists.
"why they keep oppressing the world with their Aristotelian ideology."
Aristotelianism is empiricist:
This denies that humans have innate ideas. The notion dates back to Aristotle, c. 350 BC:
What the mind (nous) thinks must be in it in the same sense as letters are on a tablet (grammateion) which bears no actual writing (grammenon); this is just what happens in the case of the mind. (Aristotle, On the Soul, 3.4.430a1).
...
These notions contrasted with Platonic notions of the human mind as an entity that pre-existed somewhere in the heavens, before being sent down to join a body on Earth (see Plato's Phaedo and Apology, as well as others). Aristotle was considered to give a more important position to sense perception than Plato
"Are they not know, that with such attitude they will suffer?"
They will not. On the contrary, Yahweh will reward them. It is their victims who will suffer. For example, look at the quantity of progress in Western medicine achieved by violently experimenting on non-humans. It is the experimentation victims who suffered and Western civilization which was rewarded with new treatments.
Again, think back to the Western air conditioner. It does not fail at cooling the room. It succeeds in cooling the room
by causing everywhere outside the room to become hotter. Those inside the room are not suffering; they are being rewarded by Yahweh. It is those outside who suffer.
