(Yes, it was also in Milani's own interest, that Keltham not be furious beyond reconciliation at Asmodeus; but that much could have been accomplished by paying a lesser price to Dispater for Dis to render those souls to temporary statues.  Asmodia would not have been broken that way, during her first time in Hell, but she also would not have been healed.  To send them both to the Gardens of Erecura is more what Keltham himself would have wanted, and paid for, than what was in the cold calculated interests of Good alone.)
