@AshiuRey well, she is probably a bas**** child, so she being the mom and a maid can be both truth... (and far too comon on these stories)

@Insight

Ah yes, but there is far more cruel fates than death (if you are curious enough look for a film called "Johnny got his gun")...

MC knows that, he knows that he saved them and they pay with betrayal, if they only let them live and not helping them, they all will suffer and be regretfull.

Kill and the pain is gone. Let them live with the guilt and having to deal with their problems without help and the pain is longer (again, the brunete is a prove of concept, being all regretfull after learning the truth, other is the white hair one having to deal with her disease and suffer a lot more now that the MC is not there to absorb the disease ).

Also, just killing them in his current level can be a lot troublesome (like dealing with the consequences of killing his master), so just let them deal alone with their problems is not a bad revenge...

@Insight

man, I'd agree with you if this was a modern society story, but it is murim, and there war far more worse reasons to kill or betray people in murim...

but back to this one, my argument is, that because they felt they were forced to be with him in their previous life, they didn't felt love for him, in fact some even hate him, felling that he was the reason of some misfortune in their life.

Like the brunette, who, in the previous life, lost the chance to be with her family because he was delaying her encouter by training her. (as far as I understand, she even had doubts if he was responsible of their deaths), of course she didn't knew the true that her family was using her and never love her and without knowing that, she betray the MC. Is she wrong on seeking revenge ? by murim standards, no.

And she is the first one who latter discovers that his intentions of delaying her was to protect her and is showing deep remorse. She is at fault? yes. The MC is also at fault? yes, for knowing the situation and now explaining properly, thinking was better for her now knowing how awfull her family was.

And I suspect that there is more to it, that someone was feeding their hate towards the MC hoping for the betrayal. that, yeah they may feel some resentiment toward him, but to make them act, someone was inciting them.

@Insight to be fair, most of them did it under a wrong pretense about him (that he manipulate them and bed them just for his lu** and sc*** with their lifes because of that) and now they saw a part of the truth (that he help them and protect them a lot) and are regretifull. The brunete is the most explicit on this (because she thought she have a loving family and she lost the chance to reunite with them because of the MC and turn out they were trying to kill her). But this looks that they were manipulated on poison him (maybe by the pink hair chick?)

@Yuuna likely, and he is distorting those feelings

@vishi

it was a weird relation, because of the neckace, he always saw his little brother as his protector, so he had a attachment for the brother he tought had died.

And frankly, he had blame, but his father had more, he was the one who free the curse, if he had not done that, the village may have resisted, the older brother try to propose making a deal, but the leader was too arrogant thinking they can defeat the empire that way. (thay can only buy time until another army with a powerfull mage arrive)

@Rick Anapaz frankly, they were already doomed, that las ac can only buy them time for he next army to arrive, or they can resist by always sacrificing kids... (and probably the empire had more armies to spare than the village had kids)

@ImmaNeet it was not her, it was one of her subordinates asking for her help

@Pipipipi

I had a  hunch when I see the guns.. the modern like tanks also were things that make me supect more...

but I like they didn't make him just a Isekai guy, but a split personality...

fell sorry for the original john doe tough...

@What the fu** to be fair to them, 1, if it was the previous demon lord they probably will win (so assuming he was on par with other defeated demon lords they were right in believing that). 2 the world may be influencing them to be like that (like we see the enginer having his eureka moment)

@J FRAME he don't deserve it, he is just a foot soldier seking revenge. he didn't do a thing against the MC

@J FRAME he don

@pikes

they may, but is like they need to be awaken probably?...

Also it is cool women can hold them, it make kinda sense.. as women have the capacity of caring and nurturing another being in her bodies (her childs)... 

@AshiuRey

Theo seems to be on his first regression by the way he was led in his first life( like the crocky master who was there to kill him before regression and how he was weak but had a lot of knowledge from working with intel), but, with power came jealousy so he may be betrayed and regressed... or not because of how op(the dragon power and skin) he is now... 

 

The question is if she got a system too (if the system is a regressor thing)

@OzTheMaverick yeah, but in a war you never know when you run out of supplies and those dead enemies begin to look tasty ( and east asian warfare had some pretty interesting stories)

@Prinzinc

no, the regrettion definelly happen, but the judgement think is pretty on mark.

She is either paying for her sins with no chance of redemption or giving a chance of improve trough suffering...

Thecnically, the deity she pi** was the MC, because when he get the judgement item, he became his ower(avatar), she and the idol pull out his eyes trying to get the item for themselves.

@karasuma

they both are in love, but diabel had a devote love, Erez is a possessive love.

 

@Introvert

she can always volunter him to the advancment of medicine (let the doctor torture him).

But for an egotistic guy like him, being arrested and knowing is only a matter of time to your public death is more of a mental torture that can really break him...

@NoNameRequired is the genghis khan logic, You kill a entire village/city cruelly, that sets a example and shows the consequences of anyone who think of rebellion.
