But that's the thing with Terminator 3 slightly changing the future, it means it wasn't a predestination paradox because the future can indeed change the past, a predestination paradox would mean that the past and future were directly tied and couldn't change each other. What i've been saying all this time is that T-3
should have followed this predestination loop, because the events of T-2 changing Judgement day means that Kyle impregnating Sarah also changed who John Connor was.
Kyle always being John's father would have meant that there's one single timeline, however, that's clearly not the case in the Terminator universe:

There are multiple timelines, and i remember McG even saying that in Terminator Salvation, in order to make sence of this all, the John Connor we saw in that film was not the same that the Kyle Reese from T-1 originaly knew.
Acording to T-3, the events of T-1, which lead to what we see in T-2 lead to the timeline being changed and the Judgement Day being delayed, however, that also heavily implies that there was at one point a Timeline A where Kyle was not John's father.
WHat i'm saying is that i don't realy like how they went with this, i would have prefered if they had gone with the idea that Kyle Reese was always going to be John's father and that there's only a single timeline. However, from all we've seen, that's clearly not the case.
