How does this change anything about the fact that being a part of Bastion is a choice? Because people sometimes fail and die? I mean...okay. People fail and die in Maldraxxus so often that there are literal piles of corpses. Venthyr casually drain souls out of existence. Night Fae choose which souls are "worth" allowing to be reborn. This isn't unique to Bastion.
I also don't really see any proof anywhere in Bastion that they force you to undergo the trials. Yeah they try to keep you from failing, but they also don't exactly imprison or torture those who fail. The only times they fight the Forsworn are in retaliation from being attacked by them.
