Let's not forget that at any point:
-not once have these criminals shown any remorse for their crimes
-have these criminals asked for forgiveness
-have these criminals asked to be taken into the village

This is the ultimate way of ridiculing the suffering of all the people whose lives got lost & ruined because of those bandits.
Instead of trying to ask the victims, and following their hopes, how this matter should be handled, instead this MC forces his own ideals onto them.
Ideals he learned from a totally different world. By doing so, he rather takes in the criminals, who should be hanged & killed, and drives away the victims, who feel even more wronged here.

NOW I REMEMBER, why I dropped this the 1st time I tried reading this.
F-you MC. F-you author. I hope you slip onto dog feces and break your ankle and wrist while at it.
Publishing this sort of excrement is a waste of paper it's printed on.

If there's any karma in this world, this author deserves to experience have his own family sold into slavery by a group of bandits (if he's ever isekai'd himseld).
Let's see if he then wants to have those guys be "rehabilitated" after he has been the one suffering from their crimes, and his own life ruined.

Just imagine some slaves in some noble's basement talking:

Slave1: Hey, you remember those guys that kidnapped us, and sold us into slavery, basically ruining our lives?
Slave2: Oh yeah, they murdered your whole family, right? And my wife and children too after r#ping them. Yeah, I remember.
Slave1: Yeah those guys. Well hear this. They invaded this other village, and tried to murder & kidnap everyone there, but they got caught instead.
Slave2: Wow, holysh*t. Maybe there's a god somewhere. At last we got some revenge for our loved ones *cries a little*. My dear, you have been avenged, thank god!
Slave1: Well, actually... I heard they didn't hang them... Or kill them in any other way..
Slave2: WHAT!? So you mean they got turned into slaves themselves? Well that's also a type of revenge I guess. The irony finally caught up to those slaving, murdering bastards!
Slave1: Well actually.... No.. They didn't end up as slaves... They are forced to live in a "Rehabilitation" center...
Slave2: What? What's that? Is that a place where they torture people until they die? A place where they stay forever from the rest of society at the very least?
Slave1: Well actually... It's a place where they teach grown people how to act and be good again... And after that, they get released back into society..

Slave2: WHAT!? Hey Hey heyheyheyheyheyheyheyheyheyheyheyheyheyheyheyheyheyheyheyheyheyheyhey wait a minute.... You mean those, murdering, no, mass-/serial murdering bastards, who räped, pillaged, assaulted, destroyed, and sold to slavery, all of my village, and a couple other villages I know of too... get to come back into society? Why?

WHYWHYWHYWHYWHYWHYWHWHYWHYWHYWHYWHY? How does that make any sense at all? Who would do such a cruel thing, that makes a joke of the suffering of all the people who died and whom lives got ruined because of those bastards...

Is it some demonlord, who just wants to see those demons, wearing human skin, back creating chaos and misery into world, is that it?
Fück you world, fück you GOD if you're watching. I hate this world and I hate you. I hope this world burns, and especially that village that took them in, and I hope the guy responsible for this rots in hell all eternity when he dies. *cries*

Slave1: Yeah, me too bro, me too..

I have a faint memory of reading this once before, and dropping this eventually.

I can't remember why, but I'm guessing it's because I dislike protagonists with soft hearts. Just like this MC, he has clearly no balls to kill anyone. Of course, I wanna see this story to prove me wrong, because this just might be a readable manga in that case.

I really would prefer if MC took the "higher road", and left the civilians alone. It's the leaders/military who attacked him and his forrest. He's just acting as barbaric as the people who attacked him first. He should try to make a point of having the control over the beasts, and that he ultimately doesn't want war with the humans.
Not really a great lesson to learn from this.

And nobody's still dead...? (I'm not counting the vice-president guy. I mean villains killed by MC & his dad friends)

It kinda takes the credibility away from this story.

It's criminal how MC still hasn't murdered anybody, or at the very least, put into wheelchair/hospital bed, for the rest of their lives.

If a young person is already that evil & violent (minor or not), his life should be forfeit, and totally worthless.
He's just gonna cause more chaos and misery in the lives around him again when he gets better.
Would've been morally right thing to just end his hateful life there and then.

This part really feels like a huge flaw in the writing. If MC acts like he doesn't like Kim Dojin's company, then how/why would KD (shortened his name for convenience) feel the need to kill MC?
And why would MC feel that his life would be in danger, if he just would kick KD from his life?
Surely, it would make no sense, for KD to kill MC, since MC's family would then become his enemy, and they would be wary of his excistence.

I get that the author tries to create tension in the story this way, and also uses it as an excuse to have the original psychopath "MC", be part of the story, but the reasons/motives behind it just completely fails to make the whole situation seem natural/believable. I just don't buy it, how MC couldn't just keep ignoring KD, until he just gave up. I get that he's a psycho, but he can't be that stupid to kill MC, because of a failed manipulation.

His natural sense to survive and adapt in new situations is plain shit.
Honestly the skill to regress is totally wasted on this individual.
He just tries to escape when he should be grinding goblins and every other possible low level monsters. (which is clearly the only route for him)

I don't really get this author. You create a setting like this, and this is type of protagonist is your choice?
The guy is just barely not unlikeable. I mean, his adaptability is shit. It took literally the 3rd time for him the get any progress in that world. And even now, when he knows he has the skill of regressing, he's constantly finding excuses of running away/not helping other people in need...
And what the hell, you know the exact countdown to the beginning of the end of the world, and you're wasting your time at work? REALLY?

Just making a point here, but making a likeable protagonist, who you can look up/relate to, is a key to success.
As if being successful creating LN's/mangas, wasn't hard enough, seems like this author even still decided to choose the harder way.

It's all fun and games, until you have to empty Samia's litter box
