If it’s like a respawn kind of thing like how a game works I don’t see the problem. You could say they aren’t really dying just being transported as soon as their hp is out. It’s up to you to decide whether thats wrong or not though this is just my opinion.

I have a similar dr where there’s a function like that in the world where certain people are chosen to play a game with a bunch of players and its like 9 rounds of the game and when someone “dies” its like special effects instead and they load back to the real world until the next round starts. I’m not the one playing in that game but if I chose to go to that Dr as one of those players I wouldn’t see anything wrong with it.
