The thing is, it’s the same but the situation is more worst right now. Everyone is fighting to protect the town, not Sakura. If Sakura goes to them the town will be saved. So it’s not Sakura is wasting their efforts because they aren’t fighting for him. It’s more like it’s the girl’s and Kaji’s situation combined. Remember how two of his friends were desperately begging Kaji not to become a monster again, not wanting him to go to use the other side of him to protect them. That’s similar to what’s happening to Sakura = Sakura will be isolated again to protect him friends and the town.
So this is definitely hard to predict unlike the girl’s situation. The town and Furin is a family to Sakura and he really values them. At first be will surely refuse but the situation might get worse and he will have no choice but to go
Oh, this is the samé situation as with the girl (the singer one), so I Wonder if he will follow the words he told her :/ everyone is fighting Hard, so he would trample over their effort if he chose the easy way out of ending the war
