Yes, however, we aren’t told WHY it happened. And Han solo’s 3rd hand report can have inaccuracies, easily.

He’s talking about his son and his best friend. I’m sure he knows what he’s talking about.

For example, here’s a take why did “the boy” do it. Note that in the movie they never SPECIFICALLY say it was Kylo. Sure, we know it’s him and they drop many hints, but it wasn’t set in stone yet. Star Wars changes huge plot point directions all the time.

I mean, it was very much firmly established at the time. All of the supporting material made it abundantly clear it was Kylo. It’s said in no uncertain terms in the TFA visual dictionary.

Anyway, this discussion isn’t productive and we’re distracting from the purpose of the topic.
