I know alot of manga are trying make the mc not kill old friends and be strong and really nice, but they make them way to soft. You would think a like 40 year old man would know that people are bad (not animals or monsters), and are not good people to friends and familys also. Like they need to live with their actions of hexing and probabilities killing someone who thinks of them a friend and good people. Maybe make this the point where he cant undo the hex even now when he gotten so much stronger. Character who are too strong and too soft need more battles lost or something. Not saving children trafficking like 10 years ago dont count.
