The part where the MC talks about his desire to actually genocide a whole race of aliens because they wronged him and his people, being 100% serious, getting into his plans to accomplish that goal and discussing it with his allies when BAM! In a later chapter he just... decides not to? Which he can do being an uber-powerful primordial race but then where did that hatred from before go??

He does say he still wants to make them suffer, and he kinda does in the end, but like how'd it go from 'I'll kill them all, I don't care what you say' to 'no, ignore what I said before, now that you've talked to me about the same three reasons that's a bad idea I suddenly changed my mind and won't just slaughter them all with my bare hands anymore and instead just kill like half by segregating them and waiting for them to die by themselves'.

You see what I mean? His hatred for the other species is still there, I won't even argue it isn't, but the visceral anger from before was missing for me, the one where he actively went out of his way to kill them and plan something that'll annihilate them in the most painful way possible.

This all would be fine if it had been a more gradual development mind you, but it came as a bit of a surprise when the last thing I knew was that he still held onto his genocidal plans even as his allies tried to talk him down and then he just decided from one moment to the next that letting them die off naturally is fine.

I either accidentally overlooked some of that slow change of mind (possible since I had to MTL the later chapters) or it just wasn't there. If we do get a complete translation that's well done and it does turn out I was just a dumbass that can't read, then I apologise and you can feel free to ignore my previous gripe.
