Isis, why?

What Isis did is really messed up. She has just witnessed the horrible things Seth has been forced to endure in order to save his son. These things may make him do terrible things later but at this point he is just a victim.

And Isis goes and curses him! And out of all the curses I think this was the worst one by far.

Osiris definitely deserves it. And really it's a good thing, she's just preventing him from doing horrible things.

Nephtys also kind of deserves it, it's reasonable that she wouldn't be able to just escape from everything after the mess she made. And suicide is just so sad, most survivors are happy that they survived. It's really a good thing for her, not mean at all, to prevent her from committing suicide.

Isis cursing herself was actually also just good for her. Osiris is obviously scum. If she knows she wont be able to stay away from him by her own will it's a good idea to make it impossible. Being with him will only bring her misery. It's kind of like person addicted to gambling blocking his/her gambling account.

But for Seth, cursing him to not have a family is just so cruel!! And he did nothing to deserve it! And she also indirectly cursed Anubis to not have a father. And he is also innocent!

Seriously, if you know your brother is raped the natural thing to do would be to stop it! And if you know you somehow can't (Osiris might be stronger) at least give support to the victim. Don't curse him! And it feels like she isn't even regretful about it. As if she's the only victim in her and Seth's dispute when she's the one who started it!! ヽ(`Д´)ﾉ

Now Seth has been betrayed by all his siblings.
