It's easy to dismiss the Templars as a cult when all they do is bicker and act petty, but what if they're not? What if they really are a shield to the innocent?
Kaija's actions have a context to them and we only know the broadest of strokes. Given that, I don't think it's unreasonable to show sympathy to her while we try to get our bearings on how this new world actually works.
See that's the thing, I don't think Templars are a cult. They are proper organization, with capable leadership and all. Problem being, they are also one with really messed up morals.
Remember that their literal orders to Kaija were to seduce MC to be close to him. That was an order at first!
Small EDIT here: Also a reason why I don't trust that bitch MC is doing sword training with. Fuck off lady. You are part of the problem, stop acting like good cop.
As for Kaija, because I don't consider Templars a cult is why I find her actions even more unforgiving.
She makes her own decisions, and she decided, not under orders, to seduce MC and let him live a life of lie.
In her own words (not love path), everything except initial friendship was a lie.
That's just INSANE when you think about it.
She willingly decided to lie to, seduce and spy on a person she calls friend.
You know that saying: "With friends like these, who needs enemies.". Kaija is very personification of that expression.
If children will suddenly go missing in the night or dark spirits will influence the unwary if the Templars were exposed and expunged, is it still so easy to dismiss her concern for their secrets? If Kaija's fellow Templars are going to be killed in the line of duty because she isn't there to guard their back, should we expect her to give them the bird so she can hook up with the MC? I don't think so.
It would make their continued existence better, yes, but it would be a necessary evil, not something MC should welcome.
And as much as I hate Kaija, MCs parents...dear lord, if something like that happened in my life they would be dead to me after all the shit is gone and they're safe. Literally gone from existence.
They valued their job over their child, to the point of ruining his life so they can sleep better at night, for his own good or whatever.
Lying pieces of shite, both of them.
