Trusting a man that could have provided the Imperium with a constant stream of new and improved Space Marines while it was in reconstruction and throughout the later millennia, but didn't for selfish reasons sounds like a smart move.

It sounds overall Guilliman doesn't have his head as deep in his own arse as he used to and all it took is seeing the results of ten thousand years of brutal dictatorship, sheer fanaticism and endless war.
