I'm an atheist so I do think it's unfortunate when people die because I believe we only get one shot at life. We don't go to cloud city and do jello shots with Jesus.
That said, Kirk getting shot is clearly a case of fuck around/find out.
If you cuddle with a rabid badger, don't be surprised if it bites you.
We don't fucking know that.
A MAGA kid shot him but we don't know why. It's possible the MAGA kid just hated his wee little face and huge head. Maybe he met Kirk and Kirk was a fucking cunt to him? Maybe the MAGA kid didn't like Kirk saying to release the Epstein files?
We don't know.
