I think it is a good debate. The difference between Jasmine and the others was her argument. Let us assume that she is telling the truth. Jasmine's argument about the deaths she caused was in her view a Utilitarian argument. There is presumably no human upside to Glory's plan but Jasmine (and Lilah) argued that either way you look at it there will be a price. Jasmine argued that although she made a choice which resulted in people's death, so did Angel. If her Utilitarian argument holds up, more people will die because of Angel, not only that, the people who do die will possibly die lonely and unhappy.
In short, Jasmine could at least present a case of justification for her actions. Whether they can be excused is debatable but most would agree with Angel that the price is too high. Also Jasmine was questioning which is more evil, suffering or robbing people of free will. The First Evil, for example presumably would bring about the end of the world, whereby people would suffer. If we believe Jasmine (and I'm not saying we have to) she was trying help people but she had a different view of how to make things right than Angel.
I'd assume that the FE didn't care about making anything right for mankind. Jasmine would not perhaps advocate what FE was doing because it would lead to human suffering. Again making the assumption that Jasmine believe she making things right for us, then she at least had good intentions, which makes Jasmine more morally ambiguous than anything else. Angel originally assumed that she simply wanted power but it possible that simply believed that mankind could save themselves from the pain we in effect have created ourselves.
From the subjective point of view, I value my free will from personal perspective and would be happy to keep my pain in exchange for my identity and ideals, however, from the inside of her influence, I'd be happier. It really depends on you values and principles. Most of us would say "I don't want to suffer" but it's more arguable what price we'd pay for ending it. Jasmine argues more than once that absolute good doesn't exist, only different concepts or indeed human concepts of good. I don't agree with Jasmine's world order but I do think that it's a argument of beliefs and concepts. Angel believes that freedom is worth pain, Jasmine cannot understand why this concept is so important if it's only a point of view and not an absolute. Her argument is that if you take away moral absolutes, you simply have a world of suffering or a world without suffering, however Jasmine takes away the choice to make the initial decision. If we want pain, give us pain.
