Guys tbh I think jaemin is not in the wrong, it's his parents, since kids normally don't have the understanding of "strangling keeps one quiet" at that age it was clear some thing was wrong with little jaemin and it's because of his parents mistake that he grew up to be a weird, reserved and not understandable ,my guess is that he is probably a psychopath like as in the disorder and the lack of remorse also explains it, I might be wrong but this is my best guess
