[Buffy the Vampire Slayer] Would it be possible to curse every vampire with a soul?

Angel was cursed by gypsies with a soul until he reached a moment of true happiness i.e. ploughing. Would it not make sense to give every vampire a soul but not have the caveat? Or have the spell broken by something really obscure like climbing Everest or something they couldn’t do like staring into the sun with binoculars.

Did Spike also have a way of removing his soul or did this not count because he chose to have a soul?

The Roma priestess did it as a "fuck you," and Willow was able to do it *while hospitalized* without suffering ill effects, so yeah, probably. Though it is a *curse*, specifically, so the anguish it causes might be necessary; the price of the spell is the vampire's pain, rather than something paid by the caster.

I think Spike's soul was a permanent fixture, as it wasn't part of a curse.
