Yeah, I'm basically repeating what's already been said but I find it unlikely that'd be he'd want hero killer dead. Telling him to "kill" her implies that he wants the peak of his ability to clash with her. As we've already seen Engen, wants hero killer by his side in important operations, as well as their goals coincide (somewhat). He's had numerous opportunities to kill and and still could. He wouldn't have made efforts to stop jintae earlier if that was the case. But I also think kill is a double meaning. "Kill" could also imply killing the current version of herself to become a new being altogether. Maybe even Engen went through a similar process to step neat the feet of the elders. With that being said though, I also think Engen chose to use kill because if she isn't strong enough to content jintae who is nowhere near elder level, then someone like hero killer is extremely replaceable and therefore unecessary. Very curious to see how hero killer overcomes this situation.
