"It's useless." Enigma did not hesitate to say what the system said. 'At least you're still here. That's a blessing and a curse at the same time, I guess.' He also thought to himself, glad that the system was still here.

"I guess it's just Fate. Anyway can we heal ya? I mean is there anyway we can alleviate your condition?" Allen did not want to stop there and tried asking again. His concern for Enigma's wellbeing was genuine.
Since Enigma knew it was useless to solve this through killing him, then he might know how to do it properly. Unless why would he say killing was useless if he had yet to try it out? This was Allen's thought process as he inquired.
