In Shonen manga, evil is determined by the intent of the doer, but in the real world evil is determined by the deed. If Kensei knew that Tanaka's wife was pregnant, and if he had the ability to escape her attacks but chose instead to kill her because of some bogus equality of martial arts bull, then he's evil to my eyes.
Love for martial arts is a lame excuse for heinous acts.
Of course, you get punished either way, and it should be the same here. What Kensei thought wasn't important, he should still be answerable to a higher authority or to a judgement by his peers. And also the difference between Satsujin-ken and Katsujin-ken. That's why it's so important for Kenichi's growth that Tanaka doesn't step into Katsujin-ken.
Chapter 124 is out.
Pretty god damn brutal.
Even when on the previous page, Kenichi acknowledges him to be a murderer "the dark one whose principle is murder" (MANGAPANDA translation.
In the reaal world, the Love of Martial arts would not excuse Murder, neither would the love of Birds, the planet (G.W.) or anything else.
In the same way, Orochimaru and Sasuke would probably get away without a trial or even a pardon. Never mind that Orochimarum is their version of Adolph Hitler's Joseph Mengele.
Wow... 524 was nasty O_O
I have to say the image of Tanaka-san with his wife and child showing them the way to Kenichi was pretty powerful
^ I agree and iirc this the first time someone died from the good side.
