Its not an excuse.
Kael doesn't know a lot of reasons why Hes is very adamant on revenge on something that happened to him.
He doesn't know Hes watched him die bcs of them and that she eventually died from grief. He had to figure some things out from clues bcs Hes wont tell him.
He just notices that Hes is making her whole life and motivation for living on revenge when he himself has moved on (he has not forgiven them - just he is happy with Hestia now).
So thats why he told her this so she focuses on her own life and enjoys it. In reality he doesn't know that Hes is technically still grieving Kaels death. So now there is a misunderstanding. Hes thinks he still cares for Diana when he doesn't. Kael thinks she's obsessed with revenge when hes moved on not knowing he died in front of her.
Diana will naturally get her own consequences without them intervening. If Kael intervenes it can stop hestia from ruining her mental health and royal families power. Diana will still be punished.
Yeah but have you read the story. She planned it yet she hasn't been feeling totally satisfied with it bcs she knows Kael has moved on and that Diana will get whats coming regardless if she did something.
Hestias main concern is what and WHO is she once revenge is completed. Shes making the revenge her only life goal and thats affecting her mentally. She will feel some type of depression not satisfaction after getting revenge. She thinks she doesn't have a right to be happy with Kael as Hestia. Thats why Kael is concerned. Ofc she is a bit outraged and so are the readers by the whole plan being thrown off but in reality, Kael is right with the limited knowledge that he has about Hestias past.
This is sucha a bullshit.
If that were the problem, he could help her after she accomplished what she worked for. He knows how much effort she puts in and she talks about how much she works for it several times.
Now, in his opinion, it's better to frustrate someone's dream ONE FUCKING DAY BEFORE IT'S DONE.
Only in YOUR head would that make things better.
Honestly, what a load of crap you try to put up to justify this disgrace.
This is insane.
Its literally not her dream. Its her revenge.
How can he help her with herself when shes too far gone?
this is literally about him so why wouldn't he be concerned. Hes not stopping her at all especially not for diana or helios. He's telling her she doesn't need to do it and it doesn't mean she can't go ahead with it.
Why don't you think of their future lol because thats what he wants with Hes whereas she thinks she wont have a future

Imagine planning a dream for YEARS, WORKING SO, SO HARD FOR IT.
And one day, before you finally achieve what you want, your supposed lover snatches it away from you.
And that's why I hated novel Kaelus.
I don't care about his excuses, that he just wants to live with Hess alone.
And her plan, something she worked hard on, and her effort thrown in the trash ONE DAY BEFORE FINALLY COMPLETING IT.
If he really didn't want this, he would have stopped it before, not ONE DAY BEFORE.
That's cruel.
It's like I was in college for 7 years and 1 day before graduating, they took me out of the course.
