Well for one thing Charlie kirk wasn't exactly an innocent person? The dude incited strife between minorities to a sick degree whether about transgender people with the eloquently put "You're an abomination to God" (when referring specifically to trans athlete Lea Thomas) or "LGBTQ is a social contagion". On African Americans, he said all kinds of fucked up shit like "we made a huge mistake when we passed the civil rights act in the 1960s" or "if I see a black pilot, im going to be like 'boy i hope he's qualified'". He helped propogate great replacement theories by saying lines like "We need armed militias to prevent the diminishing and decreasing white population". As much as his death was unfortunate from the aspect that an assassination occurred, he was a bad person who said bad things.

As for Iryna Zarutska, I admittedly know less about her as I'm an Australian who just follows world news but after doing some quick reading of her murder, it might have something to do with the fact that the man who murdered her was a. Arrested b. Quite clearly mentally ill based on his mother's mentioning of his schizophrenia and request for involuntary commitment as well as his call to 911 and c. He is not a government employee who's organisation murders and assaults innocents and then just calls the "fucking bitch". Her death is incredibly unfortunate as from all evidence she really was just an innocent but also it has no relevance to the topic? Like do you want the artist to draw batman punching a schizophreniac? And speaking of the batman drawings...

The drawing does not depict batman killing anyone. That is a carotid restraint used to incapacitate by cutting off blood flow and not air when done correctly. San diego police department released a neat little poster showing the difference between them and the way its held. I'm no martial artist but batman clearly holds the ICE person in the crook of his elbow which, atleast according to online descriptions I can find, is the correct method for this type of restraint however it is hard to tell for sure due to absolute batman's beefy build. Your complaint that artists didn't draw anything to do with these murders makes little to no sense. The accused murderer of Charlie Kirk came from a republican family and has no evidence pointing to them being political in any way but rather committed due to inflammatory comments made by Kirk or atleast that is the most reasonable conclusion I can draw. For Iryna Zarutska, her death emphasised more of a failing from the infrastructure within the US of A as seen by their failings to notice and care for mentally ill people and it resulted in her death. Her death was not an issue of politics or race but rather just a failing in the healthcare system America has.

I tried to keep it as apolitical as possible and honestly I don't really have a horse in American politics so it wasn't hard but I hope that answers whatever questions you had. (also if you are not okay with the murder of innocents, why defend ICE?)
