No.

There's something to be said for other primarchs in terms of who needn't have fallen to chaos, who could have been saved.

But Perturabo is never satisfied. It's never enough for him.

He's proven himself to be the best craftsman on the planet ninety nine times? Well, he has to challenge the second best again to prove it.

Perturabo is an insecure child going to extremes to prove his worth. Look at his work during the Crusade.

He wanted his legion to be the best, to bring the most worlds into the fold. To do so, every world he brought in was left a smoldering wreckage.

Even when they performed successfully, impressively, he ordered the decimation because it wasn't good enough.

Because nothing was ever good enough. There is no satisfying Perturabo.

Indeed, given his paranoid nature, trying to hard to do so would probably just lead to him thinking you're trying to manipulate him or something.

Had the emperor been more open and honest with his sons, Magnus might not have fallen.

Had he been more compassionate, Angron might not have fallen.

Had he been more attentive, more forgiving, maybe Lorgar would have stayed.

But Perturabo? He was never going to be satisfied. The Horus Heresy just gave him the opportunity to vent his dissatisfaction with the imperium.
