In fact, when Murphy heard the harsh terms of the frontier contract, he had a sense of unease.
The Feathered Serpent God's subsequent warning also verified Murphy's suspicion; the contract between the Sentinel Corps and these new gods seemed more like a transaction than mutual assistance.
The Sentinels used the Creator's Power to help the Star Giants step into the realm of the Divine Spirits, at the cost that these new gods must continually fight on the Subspace Battlefield until death, as long as the contract remains, they cannot retreat.
Although the new gods Murphy had contact with earlier didn't say it explicitly, the stories of Avalon and Lady Spider, as well as Vam's process of birth, all showed that this war was extremely cruel even for the Divine Spirits. This non-stop fighting scenario has lasted over a millennium, so it is quite normal for some Giants to want to back out.
After all, they are not born Divine Spirits.
