Terminator 0 Episode 5 Discussion

Ok so it definitively confirm that this anime is trash and doesn't make any sense.
There is no logic for Skynet to send a terminator back in time if Kokoro also turn on humanity and destroy them, it is doing the exact thing Skynet want to do just differently, instead of instantly blowing up everyone with nuke it send NN1 army, people who said it doesn't kill people wihout weapon or hostile behavior, my ass, it kill a whole hospital and innocent in the street and i doubt every single human showed hostile behavior toward the NN1 to "justify" the action.
The only logical scenario were this story worked was if Kokoro didn't turn on humanity, skynet send a terminator back in time to stop Malcom, why? Because he create a AI Kokoro, ally of humanity, that was able to fight/beat skynet.
Therefore future people send Eiko to protect Malcom and allow him to finish Kokoro.
However if Kokoro turn on humanity that doesn't make any f sense, what the point of the anime?
I could understand the logic of Skynet to send a terminator in the past anyway to destroy Kokoro even if Kokoro turn on humanity, because that would be a logical choice of a AI to eliminate a potential threat and eliminate a X factor, even if they want the same thing a AI doesn't like taking risk.
Instead of this Skynet send a terminator to control it? What for? Skynet destroyed humanity by itself, it's doesn't need to control anything, that doesn't make sense a AI would rather get rid of that X factor definitively rather than taking the risk to "control" it.

Not even speaking about Eiko motivation, what the point of sending her in the past from the future? Kokoro could not exist it wouldn't change shit, Skynet will still be here and the world still destroyed.
With Kokoro turning on humanity that whole story is pointless.

Oh yeah last thing, how the hell did Skynet knew of the existence of Kokoro in the first place? Can we speak about that huge time paradox?
No because in the original terminator Skynet send a terminator to kill Sarah Connor because John Connor was a huge pain in his ass in the original timeline, it didn't send it because they magically knew that in the past something was up, they send it because it had a interest to do it in his present timeline, get rid of John Connor at the source, Sarah Connor, before she give birth to him.

There is no reason for the existence of Kokoro in a original timeline since she was created to fight it after the end of humanity, the original Malcom die like everyone else from the nuke bomb wihout knowing anything it was showed at the beginning, how did Malcom of this other timeline knew about skynet i don't know but the only logical explanation is that he got back in time meaning it is already on a alternate timeline and the first time Kokoro is ever created, Skynet shouldn't have any data on it and shouldn't know what is coming because Kokoro didn't exist in the original timeline.
