Gael, after a life of grueling service as an undead slave knight, killed over and over only to be resurrected and sent back into the fray, was kept sane throughout his ordeals only by pure willpower.

Indeed, when he first asks where Greirat has gone off to, he immediately tries to play it off as being interested in looting his corpse, though his concern for Greirat's safety is audible in his voice. The implication is that Patches dressed in the armour and pretended to be Siegward because he didn't want his reputation as a no-good scoundrel tarnished by being seen doing a good deed, even by/for the one person he actually likes. No matter who is sent, Greirat will credit his rescue to Siegward upon his safe return. To send Patches, you have to not buy even a single piece of the set and tell him where Greirat is. To send Siegward, you have to buy all the pieces of his armour set from Patches (who stole it) and return it to him, then speak to Siegward in Irithyll.

In Dark Souls III, Greirat the thief will die if you send him on a pillaging run into Irithyll of the Boreal Valley unless you send either Siegward or Patches to save him.

Now, Cuphead and Mugman owe nothing to these bosses who were probably not very good people, and they would benefit greatly by becoming the Devil's henchmen, but refusing the Devil's offer leads to the brothers instead burning all the contracts and saving all the bosses from having their souls taken away. When Cuphead and Mugman finally face the Devil in the final level, they are given the choice to hand over the soul contracts they collected from defeating every boss to the Devil and join his side.
