Gone
You can opine all you like that he was acting in self-defence - but that's a legal term and, in fact, he was not. You cannot accidentally act in self-defence. You are either under the impression that you need to take action to save yourself or you are not.
And it's not enough to say "Ooops, I thought there was a burglar" when you cannot actually show why you thought that AND why you decided that death to the "intruder" was your only way out.
He heard a noise. That's it. I am sure anyone would be scared hearing a noise at night - but virtually no one would head towards it intent on killing whoever happened to be there.
Because, to be very clear, that is what the SCA decided that he'd done - grabbed his gun and formed the intention to shoot while still in his bedroom (before hearing the door slam or "wood moving").
No way can you justify that by saying "He was scared and SA can be dangerous". No way.
And the State's case was considerably more coherent than the defence's. They at least led evidence for everything - the defence just trotted out ridiculous claims (like OP screaming like a woman) and didn't feel the need to support any of it.
Roux's timeline was a work of fiction from beginning to end. He relied on unverified times, made enormous assumptions and conflated several events.
Most shockingly - and tellingly - this "timeline" did not even accord with Pistorius's own version. So far from supporting Pistorius is actually highlights just how much lying he did on the stand.....so much so that he was contradicting his own defence.
I've said it before and I'll say it again.....how credible, seriously, is the notion that a murderer managed to make exactly the same sounds his victim would have made if she hadn't been unaccountantly struck dumb?
And how credible is it that four witnesses all mistook a single voice for two and a male voice for female. All four of them. At the same time.
Don't be ridiculous. He murdered Reeva. He knows it and 99% of the rest of the world knows it.
Oh....and I agree with what Roux said at the appeal hearing. How likely is it that OP just decided to murder an intruder in the middle of the night. Not very likely at all. That's because he didn't - he lost his shit and murdered his girlfriend like so very, very, very men do.
