@ 37.152.33.225: The Lion never sided with Chaos during HH. That's a fact. Noone discuss that.

As well, we know chaos has different ways to corrupt, flirt, or fool their targets. Astelan commands the planetary defences to open fire, and he was not tainted by chaos too. Luther become corrupted by chaos.

The Lion was not sure that on Caliban all the DA were turned to Chaos. He supposed so because  they open fire and went so mad the command a massive orbital bombardment of the surface to the point of cracking the surface of the home planet of DA. Astelan was not sure about Lion's side, and he opened fire, but never for a moment he wanted to help Horus with that action. Pre-Lion Astartes were chosen by the Emperor itself, so they were not so easy to be all turned to Chaos. It's quite clear there were a large number of Loyalist (to the Emperor) that died on Caliban by the hand of Lions bombarment. After all, we know there were large number of Loyalist even in the legions were their Primarchs openly and happily joined Horus.

Magnus the Red want to warn the emperor (good intention) in the end he did a service to chaos he cant repair.

Lion would destroy traitor DA, but his actions killed many loyalist, help destroy a DA home planet, delay his arrival to defend terra, and did not even stop Luther in duel. Nothing so "FUBAR" like Magnus, luckily for him. But the scars left are still open today.

Looks like the Lions does not need to be corrupted to do questionable things. Surely guided by good intentions, but sometimes very instinctive and full of overwelming emotions.

In the End when Boreas reach Astelan Planet, he ordered to stop firing and accept to be taken into custody to prove his loyalty. The Lion prefer to destroy Caliban without even try to gater a picture of how things are. He was a Primarch after all, a very suceptible one.

So, i can agree with you there is not even one clear proof he did all he did on pourpose to serve Horus cause.

But we still can discuss about his actions, and how some of them favour the Horus plans instead of counter him.
