The "nature of our world." Interesting rationale. Here we have a religion in which the god is supposed to have created everything, the entire universe, and is in control of it all. So, that god IS the "nature of our world" according to Islam. Therefore, that god created the oppression, tyranny and bullyism, but then orders HIS creations to go out and kill one another, "in defense" and "for the sake of God's satisfaction."
If the god of Islam is so powerful, why can't he fix the problem he himself created? Is it because he is evil and enjoys the killing, or is he just a figment of someones imagination, and the holy books of Islam were written for the people, by the people of that time?
Are you implying that Jihad onyl means fighting, as in physical struggle? Then youre wrong. This argument that God created everything so he created suffering is an old one that has been adressed time and time again iirc.
