What is said on the screenshot is not equal to Astarion it is Cazador 2.0

Because this is canon confirmed first by Larian's writers: "horrible place", which means it's canon the Ritual is a bad thing for him.
Welch's opinion on the matter.
and the most important: Astarion's own confession that he wanted to be "just like Cazador". When he stays Spawn, he thanks Tav for talking him out of the ritual several times, he is extremely happy and says: "You saved me from myself" and admits he wanted to be "just like Cazador" and this is one the reasons he wanted to do the ritual. It's canon, yeah, absolutely.

(and not to mention the whole scene with the Vellioth skull)
