I agree with what neithan02 poster earlier except the last point. The sides of good and bad are not neccesarily used in WH40k but rather the duality of order and chaos. The chaos gods are of chaos and would of course want to spread it as much as possible.

As for why he would make a deal with the 4 is made because maybe he never had any intention to honor that deal. That what i could guess from the statements provided is that he needed a method to artifically place psychic powers into the primarchs. It is stated throughout the HH series in both novels and shortstories that most of the primarchs are potent psykers (maybe even all) even the ones against witches like mortarion in deamonolgy. it just so happened that Magnus was the closes to the emperor in terms of power.
