Lucifer was stunned by Luna's question. He couldn't imagine her asking this question.
"What do you mean?"
"I saw the way you killed someone today. You didn't feel any regret or fear when you killed someone. It was as if you had killed someone before."
Hearing that, Lucifer immediately remembered the time he and Luna met in Hell. At that time, Lucifer and Luna had killed two guards together to get their uniforms.
Perhaps she was trying to confirm whether Lucifer was an Esper or not. Since she hadn't asked that question recently, Lucifer was a little caught off guard, but luckily he was still alert enough to realize her trap.
"No, this is my first time killing someone."
"Never mind. What I want to ask is, do you still intend to kill people in the future?"
"Well, if I have no other choice, I still have to do it."
Luna looked at Lucifer seriously:
"This time, the people you killed were bad guys, but will you kill innocent good guys in the future?"
