I hate the argument that Silco always viewed Jinx as a weapon because it makes no sense. The concept lacks logic. And I've made a post about this before but I gotta say it again bc it pmo.
Firstly, if you think Silco viewed Jinx as a weapon, you must first ask yourself why? Why would Silco perceive her in that way? And you could have a couple of responses to that question:
A. Because of her ability to make weapons like bombs and guns
B. Because of her skills with a gun
C. Because of her emotional instability
Regardless of whichever is your answer, you must consider this thing first: Jinx is a child when she first meets Silco. This means that she doesn't yet have the ability to make guns or bombs.
"But what about the monkey bomb," you might ask? Well, we all know that the only reason that the monkey bomb is successful is because of the ammo it uses: the hex crystals, a magical, unstable crystal of great power. One crystal alone falling off a table was enough to make part of an entire building blow up. Jinx used at least 3 crystals to power the monkey bomb. So the bomb itself is not the reason the bomb works, the crystals are what makes the bomb work. And everyone seems to be aware of this, hence Jinx and Silco's reactions to the hex gems years later. Jinx is able to make effective weapons in the future not because she's always had the talent, but because she grew her skillset and kept refining her process.
At the time of meeting Jinx, Silco had no reason to believe that she was capable or talented at building weapons of mass destruction, and her ability to do so wouldn't come for years later. So at the time of meeting Jinx, there was no reason for him to view her as a weapon he could use and mold.
As for her guns? Jinx doesn't make or use any of her own guns as a child, so this is not a skill she could have displayed or a skill Silco could have witnessed when he first met her. Her ability to use a toy gun at a game doesn't mean she's gonna be the greatest marksman with a real gun. Again, this is a skill she developed with time and again, this is a skill Silco couldn't have possibly known about upon meeting Jinx. ADDITIONALLY, in the future, no one even uses Jinx's guns OR bombs besides herself. So she is not supplying or creating weapons for Silco and his crew.
So now we're down to C, her emotional instability. Jinx's emotional instability can be a great asset as it makes her threatening, menacing, and unpredictable to her enemies. But it also does the same for her allies. This character trait of hers is uncontrollable, and without control weaponizing jinx's emotional instability is ineffective.
So there is no genuine reason for Silco to have always thought of Jinx as a weapon, when half of the things she's known for she either couldn't do at the time of meeting Silco or Silco didn't know about any of those skills until years after knowing her.
But let's say you're not convinced, let's say that you believe that even if Jinx did not have any skills that Silco could have known at the time of meeting her that were obvious that she could one day be a weapon, he manages to see her as one later on. By believing this you admit that it is impossible for Silco to have always seen Jinx as a weapon, because he had no reason to view her in this way upon meeting her due to reasons I've already discussed. Which then begs the question: If Silco did not see the intrinsic value of Jinx upon first meeting her, why did he keep her around?
Silco, very clearly, does not care about his employees. He, at times, manipulates them to do what he wants, he puts them in danger, he is physically violent with them, and he does not care for the most part whether they live or die. The only two employees that he gives the slightest shit about are Sevika and Jinx. I say this to say that Silco's employees are clearly no one special, they are easily replaceable, he is not hand selecting them (at least not later on), they are just normal shmucks he takes advantage of. It would be out of character for him to not only take in a child, but dedicate years of effort into grooming her into being "the perfect weapon" when he A. Has no idea she has skills worth weaponizing and B. Does not typically go out of his way to condition his employees into working for him and being his pawns. This decision is seeming for trouble than it's worth, more risky than the potential reward could ever justify.
Additionally, Jinx has been a major fuck up her entire life, both before, during, and after meeting and knowing Silco. As a person, she's known for being unpredictable and unstable. As an employee she's known for being unreliable. As an enemy she's known for being a loose canon. She has fucked up tons of times while on the clock for Silco. If she's supposed to be his weapon, she's ineffective as fuck because she isn't reliable. Not only that, but her unpredictability makes her a threat to the rest of his employees, the ones that actually do their jobs. So even if Silco decided to groom her into being a weapon, it doesn't make sense for him to keep her around once she's an established fuck up who can't be controlled and can do serious damage.
So just to summarize: you can either think Silco always saw Jinx as a weapon or you can think that he later saw her as a weapon/developed her into being one. It doesn't make sense for Silco to have always seen her as a weapon when he didn't know she possessed skills that could be weaponized upon meeting her. It doesn't make sense for Silco to view her as a weapon later down the line either because she becomes so unhinged and uncontrollable she cannot function effectively as a weapon. On her best days, she's a fuck up who gets the job done anyways and on her worst days she's costing Silco things that never should have been lost in the first place. If Silco was grooming Jinx to become a weapon, not only did he fail due to what I just spoke about, he was always taking a major risk considering Jinx's skills as a weapons maker and a marksman were underdeveloped and would take YEARS of refining to get to the skill level we see in the show. Ultimately this risk isn't one that he needed to take, and Silco does not have a history or past of hand selecting and grooming Jinx in the way that's being alleged, so this doesn't make much sense either.
TDLR no matter which way you argue it it truly doesn't make much logical sense for Silco to see Jinx as a weapon
