if he told her the truth about who he is, he could have just told her he forgives her for shooting him. I am sure if she knew that Joon forgives her and that he is in heaven she would be able to move pass her guilt eventually without Black having to sacrifice his whole existence.
i believe so myself, he really should have told her about everything and helped her understand who she is, what she can do and how to forgive herself. this could've went so much better for both of them. it just could've been handled in a smarter mature way to help both of them. i think if she understood who she is and what she can do can make a huge difference

tendele:
well to be fair even if he did not chose it himself black would be punished as he killed. (remember the baddies after rescuing ha ram from the pool)
i think he only killed after he made that choice. he only knew about the punishment and then choose to kill to try and get the ultimate punishment as a sacrifice for her. so if he really didn't plan on that punishment he could've avoided the whole killing people and punishment thing.

tendele:
and for ha ram i believe black did not just wanted her to forget it all as having killed someone (and moreover someone you love) is not something one can forget just because the dead himself told you it's not your fault. that would be with ha ram all her life even if he stopped her from jumping from the cliff and told her to live.
it's not about forgetting, it's about forgiving. him being there for her and helping her also asking her to help other people can make her do better and be a better person. she's a person who has to deal with death and can help saving people from it so if he helped her she can even deal with it in a more productive way.

The show stated that he made it so the accident never happened. Therefore, she was just a normal girl with a normal life.
i really don't get that. the accident had nothing to do with him was it as a grim reaper or was it as joon. and the punishment has no power due to the fact that it is a punishment, so he had no power to change the history as he may please.

Maya:
And I don't understand why at the end Black was here, if he erased his existence he's not supposed to be dead, so he can't be a gream reaper ? If someone can explain because I'm confused
exactly what i was thinking. was his soul "deleted" or the history changed so he wouldn't exist. him being a grim reaper or moving to heaven makes no sense
