I thought we were just sending out invitations to the Eye of Terror so the loyalists can join us for a fancy dinner party.
I always found it very rude of the Inquisition to murder our new friends, but at least they arrive pre-roasted.
If the loyalists wipe us out and the xenos out then they have no job to do, we are breed for war and with out us you might as well kill each other. You can't have light with out darkness. Its a never ending cycle.
Then they will become they very thing they hate and it starts the cycle all over until all space Marines are dead every last one. Then it goes back to normal humans fight one another and they slowly start losing all the planets they took over and they you are back to square one and some new guy is going to make himself the new emperor and start this whole war all over again. So chaos will forever be here because its fate.
