End purpose of Islam

We all know that Islam was brought into this world to bring peace and brotherhood in this world but on the other hand from Hadiths and other sources, we know that till the end of times, there will be war and chaos and there will be coming of Imam Mahdi and Prophet Isa and Dajjal as they will come at the end of times when there will be lots of battles and fights. I see this as a contradiction because on the one hand, Islam was brought to bring order to life on Earth, and on the other side we see that till the end of time, there will be battles between people of different religions specifically Jews. This clearly shows that till the end of time, there will be existing non-Muslims and Islam will not be a global religion. Isn't this similar to the fate of Jinns when they used to live on the planet and at the end of their time Allah SWT sent angels to fight them and eradicate them from the planet and then brought Humans on Earth? If that is true, then aren't we the same as Jinns and no better?
