that bitch was blocking him with her body, he tried to walk around and she pushed back against him, that's assault on her part.
Right, but its not an assault justifying the use of deadly force. Its a low-level misdo battery.
You've not studied the law. That's clear.
His use of deadly force was in response to being attacked by an armed male at some point later.
The armed male (with skateboard and drawn knives) who attacked him was not privileged in the law, as you seem to believe he was, to murder him under the justification that he had, moments earlier, used
justifiable force to defeat the woman's unlawful use of physical force to impede his progress.
