Depends on if he keeps him or not
Spoiler
He doesn't..

The ant is a way better healer. So him letting Hunter Min go is fine.
Dont know whether he is gonna let him go or not. It just seems like the more humane thing to do.
He let him go, I've read the LN. That's the most humane thing to do. Even after reading and knowing Hunter Min's character, I think he probably didn't even want to be resurrected
Now that he got an S rank healer or his party. Won't his army become even even more OP
