Who would you side with

Lets be realistic...forget the armies you field. Assume this is happening and your a normal man not a Space Marine. Explain your choice.

are you all aware of who Horus made a pact with? The Imperium of man before the heresy was a government of enlightenment and rediscovery. horus was a warmongering narcissist who thought the average human was nothing. the emperor knew what and who he was fighting for...humanity. now we cant all assume we would be astartes in this scenario. lets look at this as a human being. horus surrounded himself with all of the primarches who had major issues(religious nuts ,psychopaths and egomaniacs) and probably needed therapy. and they all looked on humans(you and I) as nothing more than cattle. im not gonna be some pathetic cultist to be treated like a maggot or sacrifice to some demon god by Astartes. id rather fight as a soldier of the imperium and if I fall ,i fall as a soldier and free man. In conclusion...Im with the Emperor all the way.
this why I made my choice.

FOR THE EMPEROR!!! Definitely the Emperor. Horus and his heretics were all idiots. I agree with you Bill, I'd rather go down fighting as a soldier of the Imperium than a worthless heretic who is looked down upon by just about everyone else and will probably end up being sacrificed or killed just for fun by a chaos marine.

Horus was an aspiring orator able to rouse his marines and followers into a frenzy, he could probably convince you and me to fight for him. Furthermore I don't want to be part of a "grand imperium" for some OCD Emperor (you go here, my marines conquer here, this is the plan...).
I'm my own person too with a great will to survive I think I would be able to kill and deceive my way through the ranks of chaos easily.

Probably upon seeing a Greater Deamon choosing sides would be REALLY easy too!

I'd rather die fighting for my Emperor in his luxurious golden toilet than turn to chaos. You are a heretic Max and you must be purged!

BTW, what order cleans the emperor's toilet throne?

I chose the Emperor, seeing as turning toward Horus would mean damnation and eternal suffering on an unimaginable scale. I would live my life out as a servant to humantiy. I think the choice is pretty clear. None of us here are that special by the way, Max. Perhaps you would wind up a handservant to Fulgrim. Don't forget the vaseline.

i'll go with the emperor, Horus reminds me to much of castro "lets all get together and hold a big revolution to overthrow oppresion !!...then i will rule you forever as a demon god and destroy the places you live in untill your will is crushed!"

wtf, you shouldve posted Ghaskull in there !!! i wouldve sided with him, Orks are just out to have a good time !

hitler was a great orator ,but I think the holocaust was horrid. I would have never gone along with that.i would have volunteer to fight in north africa and avoided that butchery and hope adolf would be assasinated after germany won the war(im sure most germans thought they were gonna win). with the heresy you have a choice, id say the emperor is a more inspiring orator than horus. also we are talking about siding with a live tangible emperor, not the corpse in the iron lung. also lets not forget the imperium wasnt bad ...pre-heresy. it only became a nightmare after the heresy was over and the emperor was entombed. the emperor wanted to see the imperium and man flourish. the reason he went back to earth was to complete the warp gate that would end humanity's dependence on warp travel therefore allowing for the warp to be sealed of from humanity forever. this is why the demon gods made their play with horus.

Max, as phil said, youd end up a man servant to fulgrim or a slave to the word bearers. read dark apostle, thats how youd end up. your not that slick and you aint no Space Marine.
