I wish there was an interdimensional police can arrest this asshole!!

Point of the story is the Hero blackening into a villain for revenge. Don't think the twins could be redeemed. They were raised in a twisted environment to be sociopaths. Their gleeful torture and murder of animals and implied humans demonstrated their already degenerate characters. Children ccan be just as dark and twisted as adults. There are a shocking number of murders committed by young children from normal upbringings. These are not children that could be trusted in society. At best they would be institutionalized.

Then, explain to me about what if kids who are under 15 years old that killed lots people, but released shortly because they are kids/underage but after the released, was caught again for killing more? You still think because they are kids they shall be forgiven? I say better kill them for the sake of other.
What if you are a judge, and you released a kid who killed his younger sibling, then that kid who got released, killed his neighbors little friends as well? If that will be the case, I believe your name would be in the 'People MC Gonna Kill' Lists.

I not saying he should let them go free unpunished, but kept as a slave, or something teach them right from wrong, give some form of punishment befitting for them at the same time rehabilitation. But I see you're point, it'll be too much hassle, we should start killing child-soldiers, children of ISIS and other terrorist groups, cartels, and so on. F**k the civilized route. I'm guessed l'm just wired that way to be protective of kids.

Agh, another shitty anti-hero avenger trope. If he starts killing people just cuase they look at him the wrong way, then fuck this mc up the eye socket.
And why the hell is a healer considered weak? Even if they can't fight their healing magic should be extremely useful for their combatant party members. This manga doesn't make any sense it's ridiculous.

In a lot of mangas and novels the healer is considered to be weak. Yes, logically speaking, a healer is very important but if a world is built on physical strength then healers become second class citizens. The logic behin that would be that a healer is only needed when the party has very strong members and he becomes useless if the others are weak so basically his importance depends on others and the strong people are strong regardless and their status doesn't depend on others.
Again, I know that a counter argument would be that the strong members can be saved by a healer and all that but I say that it makes sense that for some people, healers aren't as important especially if they went through the trouble and sacrifice of summoning them from another world. We don't know the whole story, for all we know, maybe healers are everywhere and physcially strong / people with strong magic are harder to come by...
But I do agree that it'd be a turn-off if he starts killing everyone.I don't think the manga'll take that road but I do hope he eventually bloody murders every single classmate of his since they all basically tossed him out to die since they were stronger so it's only right he dos the same to them when he becomes stronger.
Here we go again Humans bad, Monsters good. This trope is starting to get old and predictable.
At least when it's the monsters who are the baddies it's far more interesting how small insignificant humans can fight dangerous monsters using ingenuity, skills, and teamwork even if the humans are op. It's just personal preference I guess.
Just an opinion but to me killing humans is like killing Kids in a barrel, at first it's good for shock value but after a while, it becomes like a one-sided massacre the feeling gives me is like argh not this again. Don't get me wrong killing in self-defense and defending others is fine but even after the enemies gave up he still showed them no mercy, evil or not they could've had families what if they want vengeance. He's no better off now when he was killing monsters and orphaning their kids. I guess that's what really irks me. But it's to be expected in a human turn demon king manga.
Well, in almost all stories that monster are bad humans are good, humans still kills monsters that are good or only following orders!!!
I feel the troupe of humans being the bad is refreshing, but many people hate it because people don't like stories of himans being killed!!!
Also, monsters have families!!!
I prefer the stories where both humans and monsters are both good and bad. this one makes ALL humans one-sided-ly bad and that is irritating. If you want a story where monsters are good then there has to be good and bad on both sides.
That's why I hate this. It's like all humans are bad and demihuman are all good. And that fat sack of shit kills his own kind when he could just as easily restrain or knock them out.
Well because humans are greedy creature.
I'll say, it's true most human these days are more evil than true monster
I agree...though we try to be altruistic, humans are in essence greedy and selfish. Now that all depends on the amount, and whether we can rein it in. Also, the way the humans act in the manga seem to portray the way colonists were in the Americas where they assumed they were the superior race and etc.
that can be applied to demi-humans, every single one of them being this kind and accepting is just bad writing
IKR they over hype the humans as bad guys while overly made the monster sweet, kind excepting, and lovable. Can they portray that some monsters love the taste of human flesh which why so many adventurers fight them? That Shows that evil can exist on both sides. And personally, the ML is a frickin idiot, no wonder he relates to those dumb monsters.
