Arno elaborated
"The first problem we have is the change in your aura."
He asked
"Do you know what changed?"
Leus shrugged
"No, I have no idea. I really feel no change"
Arno took note of that and continued in a neutral voice
"It's your regard for life"
Leus furrowed his brows
"Regard for life? What about it?"
"It has declined"
Leus genuinely didn't understand, so he asked
" ... What do you mean?"
Arno leaned over the desk, getting closer to Leus
"You might not feel it, but your regard for life, as in valuing life itself, has decreased.
This means that without self-control, you may reach a point where you consider taking lives an ordinary act."
His tone turned solemn
"Set boundaries and create rules. Create a Moral Code and follow it."
He leaned back in his chair again
"Honestly, I do not have the moral high ground to tell you how to use your powers, but as your Mentor, I suggest you control yourself and think before you act—for your own good."
