Why you say that? There's nothing she could say that would warrant a person who calls themself a man hitting a woman upside the head with a brick, but it's 2023. We've seen these women. The likelihood that she just said "no" and that's it, and he hits her with a brick isn't likely. She doesn't even have to sugar coat it "sorry, I have a man" "sorry, I'm not interested" "no thank you". She doesn't have to explain or sugar coat shyt. If she was like " fukk outta here, your dusty, you ugly, I don't want your ugly Lil dikk ass!!!!!" And tryin to clown, he might've of grabbed a brick, most definitely a bytch move and not justifiable.
We want to pretend she was

all nice, sweet and innocent and this was some deranged unruly animal, but that's not likely the case and everytime in any interaction whether fight, robbery, domestic, murder, road rage, etc, that's usually the case that both parties were out of pocket and one upped the ante.
Hopefully someone finds dude and introduces him to the working side of a sledgehammer in front of any family he has and if he dies, he dies.
