It sounds like you might be interested in the idea of a PvP multiplayer game. I've never found myself concerned with the morality of camping/flanking/wiping an entire squad in BF6 without mercy because I know they urgently wish to do the exact same thing to me.

But one where death is permanent / seriously bad; in Battlefield you just respawn so dying is not a major issue.

World of warcraft and battle royale variants exist. One life across a 90 minute game is pretty high stakes, relatively speaking.

Check this one out: It's a F2P war game that ships with every new console. You only get one life in the game, so if you die, you can't play it anymore. It's not required to play, but heavily encouraged since it comes pre-installed.
