Look here that's because his sister is a hunter and he is now trying his best to make the world safer for her while improving her abilities. He can't tell her to stop being a hunter now can he? While he was gone his sister had to fight to survive. Suddenly telling her not to fight is the same as telling a chef they are not allowed to cook because it's dangerous. On top of that how can he protect her and his mom 24/7? His selfishness is not coming undone. He is selfish and I think he will fight again after knowing another unidentified being is trying to fuck up his world.

When I said it was coming undone in season 2 I didn't mean anything with his sister nor that his selfish act was coming undone. I meant his act to protect the world by erasing nearly everyone's memories of him, Sisu, and all that he had been a part of from everyone was coming undone. Meaning even though he wanted to hide his power, his ability, his near world shattering strength so that there would be no fight for him or threats to his family since he will refuse to leave. He didn't want anyone to be put in harms way because of him, but he's the very reason they're in harms way in season 2.
I'm saying his very act to keep everyone at a distance is coming undone. I know my sentence did leave it very misleading to make it sound like it was his selfish desire that was coming undone when he just continues his selfish path all the way through xD

Oh yes I understand but technically it's not because of him but that other being was the enemy of the the unidentified godlike monster so mc doesn't know he is related to the source and our girl is useless too I guess. How can she not sense her enemy or maybe erasing memories took a toll on her.
Haha it's fine and yes XD

Erasing everyone's memories of him was a bad move. You can erase the memories, sure. But not the effect he had on the world. And simply erasing memories without putting anything else in their place will leave people wondering why they have missing memories. Even obsessed people like the old man. As has become evident in season 2. Where all of his allies clearly didn't "forget" him completely, even if they don't remember him. Or the old man making it his life's mission to find out what happened to everyone's memories.
It's understandable, kinda. Kim's only human. He couldn't foresee what would happen in the future. And in the first place he was thrown into the "tutorial dungeon" against his will. All he wanted was a bit more excitement in life. Not to be tortured for 3000 years to then become the strongest person and savior of humanity. He only kept fighting first as revenge, and then to make the world a safe place for his family. Of course he'd want to actually be a normal family again when he saw the chance.
Am I the only one who thinks mc is really human for erasing memories. Like he was tired of fighting and only wants to protect his family + humans are bothersome like even heroes can have haters and psychos who wants to prove they are better than him or scientist and researchers who wants to experiment and know about the powers of those unidentified beings. There are so many dangers to him and his family apart from monsters. Some people would even blame him if he prioritized saving his fam over 100000 people lmao. Still things are going the wrong way because of that meddlesome old man and that another monster.
