I think he was pretty clear actually. He fired when he thought the door was about to open, in fright and without time to think. The problem I think is the word
intent. OP is clear that he didn't think before shooting and that's why he says he didn't have intention to shoot. This is an understandable perspective when the word is used colloquially and is surely different from
intention when used in a legal sense. Given that OP was consistent about his version regarding the belief that the door was about to open, that he was afraid as he thought there was an intruder and that just fired without thinking, the question of legal intent should have been decided by the court and not OP's answer to the question of whether he intended to shoot imo. Masipa decided there was intention so PPD should have been based on that finding, not on OP's fuzzy and colloquial understanding of intention. In effect he had one version that could raise 2 possible defences depending on how you dealt with it legally.
Try looking at the excerpts from this perspective: see my bolds
Roux: At any time did you intend to kill reeva
Oscar: I did not intend to kill Reeva or anybody else Mi'Lady.

Oscar:
It was accidental. My understanding is I didn't intent to shoot the intruder. I got a fright from someone inside the toilet.
Nel: You never fired at the intruders intentionally, the gun went off unintentionally?
Oscar:
I didn't have much time to think. I dealt with a set of circumstances.
Nel: you're giving evidence. Did you shoot intentionally?
Oscar:
I shot out of fear.
Nel: Because of fear you shot at them.
Oscar: I didn't intend to shoot at them, I didnt intend to kill someone.
When I heard the noise from the toilet, I thought someone was coming out to kill me. I didn't have time to think.
Nel: Did your gun accidentally go off or did you fire at the intruders
Oscar:
My firearm went off, it was an accident it happened. I fired my firearm before I could think
Oscar:
At the time I fired the shot, I didn't have time to think. I didn't intend to shoot at anyone. I can't say I didn't.
I never fired shots purposely into a door.

Nel: Did you fire deliberately, still accidentally.
Oscar:
I'm still that I fired the gun out of fear. I didn't mean to pull the trigger so in that sense it was an accident.
Nel: I never meant to pull the trigger. You never wanted to shoot at intruders coming out of the bathroom.
Oscar:
I didn't have time to think. I didn't want to shoot at anyone.
Nel: Whatever happened never caused you to shoot - it happened accidentally.
Oscar:
The noise came from the toilet, caused me to pull the trigger. I didn't have time to think about it, I heard a noise, and I discharged my firearm.

Oscar: I didn't intend to shoot,
when I heard a noise, I didn't have time to think. I fired my weapon. It was an accident.

Nel: If you did not want to shoot the person, what did you want to do.
Oscar:
My intention was to make the person flee.
Nel: Nothing else.
Oscar: correct
Nel: And when you got into the bathroom there was nobody there.
Oscar: correct
http://live.nydailynews.com/Event/Os..._Death?Page=55
Nel: But isn't your defence that you thought you were in danger and wanted to shoot the person in the bathroom.
Oscar: No
Nel: Is it your defence that you fired at the perceived attacker.
Oscar: I fired at the door
Nel: Is it your defence that you fired at the perceived attacker.
Oscar: No.
Nel: Then what is your defence
Oscar:
I heard the noise and I didn't have time to interpret it and I fired my firearm out of fear.
Nel: I don't understand your defence you can't have two
Oscar: I understand
Nel: The way I understand the defence is that you acted in putitive self defence. that you fired at the attacker to ward off an attack.
Oscar:
I didn't have time to think. I fired my firearm.
Nel: you defence has changed from putitive self defence to involuntary action.
Oscar:
I don't understand the law.

Nel: IF your version now is that you fired because you were scared? Why only four, why not empty the magazine? Why not fire at the window. Did you not think there was someone on the window.
Oscar: My firearm was pointed at the door.
Nel: Did you not think of firing into the shower
Oscar: If I fired into the shower it could ricochet and hit me.
Nel: But firing into the door you should know it could hit someone.
Oscar: I didn't intend to fire my gun.
Nel: you thought the intuder was coming out, and they would have to turned the door handle. For them to get out the door they have to use the handle, and you could see it.
Oscar: I guess I didn't focus on the handle, I focused on the door as a whole.
Nel: Did you not fire at the handle.
Oscar: I can see that is not the case
Nel: If you wanted to fire at the intruder, where would you have fired.
Oscar: Probably at chest height, probably on the right.
Nel: So we can exclude that you fired to protect yourself.Did you fire to shoot an intruder.
Oscar:
No I fired because I had a fright.
Nel: If there was an intruder in the toilet, would it have been an accident.
Oscar: I never intended to shoot anyone, yes.

This all seems very consistent to me.
