The real point here is that he was not in danger until he sought it out. He didn’t suddenly find himself a bystander in a dangerous situation, he went out of his way to place himself there. He actively sought this situation out, placed himself in harm’s way, put in active effort to get himself involved. He then acted like he was just defending himself when he found the exact situation he’d been actively seeking, just so that he had a convenient excuse to shoot some black people.
It seems pretty clear that if he can’t have it, he’ll do his best to make sure nobody else can either.
