I think he wanted them to take over for him and work for him but knew he wasn’t beating them. So instead of fighting he set up contingencies so that if they killed him, he could go thru whatever he needed to step by step in order to survive again. The new version would know everything he did to get to the end of time and replicate and improve on it thus sending renslayer to join him next tjmemaybe but he told them killing him would unlock the door... I mean he even had transcripts of the entire conversation... its like he wanted to die...
