Hi Anon! Okay so, seeing how Ciel totally blames himself for what happened to his brother…

I don’t think he will be able to face him at first, so I doubt he’ll be able to order Seb to take care of his twin either.
In fact, I hope that Seb will be absolutely irrelevant to how this confrontation will turn out for our!Ciel, because we know he’s not particularly good at being sensitive and helpful whenever our!Ciel faces his trauma (ch95 anyone? -_-).
It’s as I wrote here, I think this arc is supposed to help our!Ciel with confronting most of his issues surrounding his trauma and what happened with his brother, so I don’t see how Seb is supposed to be the means to an end here (unlike all the previous arcs before), not when he’s the one who ate the twin’s soul in the first place.
No, in my opinion, if the twin is to die before this arc ends, then I think it’d make a lot of sense for him to be stopped by anyone but Seb.
Obviously, right now the most symbolic ending for the twin would be to be stopped by our!Ciel himself, since that’d also imply that our!Ciel found enough strength within himself to face his brother despite how much he was blaming himself for his death, and a catalyst to such an ending could be Lizzie herself.
I mean, if the twin hurts/allows someone to hurt Lizzie (which I think is likely to happen) then…

…in my opinion it could be shocking and despairing enough that our!Ciel would realize he has to stop his brother.
Other candidates for the same job would be Soma (since the twin attacked him and Agni), Lizzie herself (since she realized a while ago in ch113 that she “couldn’t save the twin”), Ed possibly (if he’s angry enough should Lizzie be hurt) or Tanaka (since surely he’d notice that the twin hardly is the boy he used to be).
So nope, Seb killing the twin again would just… not help our!Ciel with the fact he’s constantly blaming himself for what happened to his brother.
Seb can go face the other star Lords (like Polaris, who’s real!Ciel’s butler and who apparently was strong enough to kill Agni), or the mastermind behind the arc (UT? someone else?), but the twin isn’t going to be his call in my opinion.
I hope it answers your question, have a nice day Anon!
