After reading this twice.. and certain parts more... It seems the MC was going to let both of them live. But neither of them wanted to betray their family and he said he family wouldnt be able to rest in peace unless they were all killed. So she let her husband kill her(or suicide?), He then killed himself since he didnt want her to be alone. He apparently did love her. The MC came racing back when he sensed that either she or both of them were dead. it seems he then extracted only his soul and rather then making it into a devil boss, he put it in the body of a pregnant lady so he could be reincarnated. Im not sure how much of this was left out of the story, but id like to think he saved her soul too, She did die which is what he wanted initially.. but sometimes such things get left out, so maybe she was saved too? A novel reader would likely know far more.

@ThunderaMaou The families dont really deserve to die, but its what their family leader(?) did to his entire family, all over nothing. But this is why they wipe out entire families, because if you dont, someone will grow up and come for you. If he left them alive, who knows when or where they would turn up. That said, in these worlds death isnt the end, they reincarnate etc. In a way death is simply losing their memories and starting over as a kid, not so much "death". For certain people though their souls do get destroyed or tormented for all of time as punishment.. in such a situation, death by itself isnt that bad. In fact, the leader of that other family killed his entire family and stored their souls in a soul flag and then used them in combat because he was a evil person. The MC isnt even doing that UNLESS they are one of the top few strong people.
