Improving Miles Morales

Miles Morales, in my opinion, isn't that interesting of a character or a spider-man. To fix this, all we have to do is change his origin story and the rest will follow. Here's my idea of a revamped origin story.
Miles Morales is teenage criminal whose been put in jail multiple times by spider-man. He has a burning hatred for the hero since doing crimes is how Miles supports his poor family and himself. On one day that spider-man is facing multiple villains (could be the sinister six), Miles sees an opportunity to take revenge on him. As spider-man is dodging and evading so many attacks, Miles takes his gun at and gets that one lucky shot that spider-man doesn't see coming. Miles goes over to spider-man and gloats about his revenge and talks about how spider-man is a hypocrite for claiming to help others while severally damaging Miles' family. Spider-man then tells Miles that he's happy to finally help his family and dies. The villains congratulate Miles and reward him handsomely for his services. After using his rewards to get his family and him a nice house and gifts, they are robbed and his family is killed while he is out. Miles' actions has thrown the city of New York into chaos since its most famous defender is dead and now he sees why spider-man was so dedicated to stopping crime. Because of this, he decides it's his responsibility to fix things so he gets himself bitten by a radioactive spider and becomes spider-man.
He can have the same powers he does in the normal comics, but the struggles he goes through are different. Miles has to struggle with; coping with the loss of his family, getting to know other people, being responsible for the crimes he's committed, seeing the good in him as he tries to fix things, and trying not to kill.
This would make him the best spider-man since not only did he kill the original, but he also has the most to make up for, the most to learn (which can lead to a lot of moral lessons), and the greatest responsibility. In my opinion, this is a better and more interesting Miles Morales. I call this spider-man, Venom Stinger Spider-Man or Venom Spider in reference to one of his abilities (name could probably use work). Tell me what you think if you have any opinions about this and if you think this is interesting.
