OMG
Master Chief w/o his Helmet!
Stosh <3's me vicariously... at least someone does...
Well I just went to the toilet to have a good think on this, and I think I've found a pretty good explanation.
It's the same reason Cortana wanted the Gravemind to go to the ark.
Halo wouldn't have killed Cortana, but it would have killed the Gravemind (much more thoroughly than destroying High Charity would have, as evidenced by Halo 3). She (still being around post-firing) could have then destroyed the Halo, which presumably would have stopped the signal from being amplified, thus limiting the pulse to the Delta system. Chief was already gone, and the humans on the Halo would have been dead anyway, so it really wouldn't have been a tough call.
That said, High Charity becomes a plot hole after MC leaves. It somehow travels all the way to Earth with no power supply, and apparently the Gravemind was so catastrophically inept that he decided not to send any spores anywhere but the Ark. Then again, at this point this is Halo 3's story we're talking about, so don't even bother.
