The challenge was basically 'vote to kill other teams so your own team doesn't die' and for various reasons Curtain voted to kill Jae's team, everyone did, his team was winning the most at the time, so then Jae and everyone on his team died.
It was temporary, like in this place, everyone knew it would be temporary. Jae wasn't mad about it. Curtain felt really bad about it but instead of saying he felt bad about it he just acted like an asshole and tried to make Jae leave him alone, which didn't work.
