I don't know why Moby is feeling bad about Natalie. Is he forgetting she was a sociopath that killed one person and tried to kill another (only for Moby to beat her to the punch) not to mention how she tormented his gf. The only thing I can think is that it has to do with Natalie technically being part of his family before she died. Maybe family members dying has an effect on Moby
Another couple of critiques since I read this far; A question is a question . Stop using an exclamation mark instead . Also you use way too many exclamation marks where a simple full stop would suffice.And one last thing , the dialog needs work . Its just unnatural . Nobody talks like some sentences in here . I suggest to envision like you are speaking to someone rather making grammaticaly correct sentenses.
