How was Johan able to........ ?

[xfool]

I still dun quite understand how Johan can cause others to kill for him. Did he develop some kind of mind power when he is being 'conditioned' at 511 Kinderheim?

it's called brainwashing... He has a gift of manipulating people

taken from mangascreeners. interview with Lunge
At the end of the interview, I asked him about brainwashing -- how does one manipulate and control another
person this way?
"It's simple," Mr. Lunge stated. He asked me where I was currently living. When I answered Vienna, he said,
"Then, can you draw me an accurate map of the city, depicting every single road?" I wracked my brain to conjure up a
mental map of Vienna, and began drawing a simple map on my notepad, as he intently watched my facial expressions.
When I admitted defeat, saying that I could not possibly draw an accurate map, he took what I had written.
"What area of Vienna is this?" He asked.
I sheepishly said that it was the neighborhood I lived in, and he responded, "Then to you, this is the center
of the city; no, the center of the world," as he looked at me. "When you imagine the place called Vienna, you use
your living space as a starting point, and think of roads and places as they relate to your location... And even
when given an actual map of Vienna, you most likely see your neighborhood as the center."
When I nodded to show that I understood, he went on. "In the very center of your mind, just like this map,
there lies the foundation of your ego -- your identity."
I nodded again.
"But suddenly, your coordinate axis is removed. There is no meaning to this center... there is a much more
appropriate center for your heart. This is the reality of what we call brainwashing." He smiled. "And when a
human being's mental axis is removed and they are lost, you gently and carefully entrap them with words, not giving
them the opportunity to think, offering them a new place to live... You will find that human beings follow the
instructions of whoever furnishes them with this new home... They become surprisingly docile."

What he said at the end of the interview
The former detective answered, "Johan possessed superhuman brainwashing abilities, but he also cast aside
his desires one after the other... A rare type of criminal. Like... like a Buddha drawn to destruction."

From the interview with Gallen, again taken from mangascreeners.

- What do you believe Johan was?
"A man who could delve into the hearts of lust murderers. Or perhaps he could simply delve into the hearts of ANY
human being. A brainwasher who could control the minds of other people. But what he sought was not pleasure from the
murders of others. He wanted to wipe out the entire world... that was where he derived his pleasure."
- How would he actually go about infiltrating the heart of another person?
"By acknowledging their worth. By never frowning upon their actions, and by teaching them that they are not alone
in the world. They are elated, believing they have found their one true friend, the only person in the entire universe
who understands them. Or, on the contrary, he might belittle them, lambasting their every move and driving them to the
darkest pit of mental solitude and ruin. After doing that, he would simply make a little request. Just kill one measly
person, that's all..."
- If he were to awake, would you want to perform a mental analysis on him?
"As a scholar, of course, I have an interest. But, I don't think it would be a good idea. From his perspective,
I would probably be the easiest type of person to brainwash."
- Easiest to brainwash?
"Do you know why it is that I have such a reputation for my psychological analyses of serial killers? It is
because I am very similar to them, and thus I understand them well. The reason I have such an interest in them is because
I want to know more about myself. I believe that Inspector Lunge could say the same. Everyone involved in that case,
with the exception of Tenma, was fascinated by Johan. They were all similar to him in some way, all very easy for him to
control."

Hope this answers your question

[Liflime]

He tells the stories, told to him by Franz Bonaparte, to the people he wants to manipulate. And by that, the story itself is the one that makes the brainwash effect on people. Lol, I ain't sure if that's Johann's strategy.
