I think the most comforting way to take it is that when someone thinks “i could throw this drink and kill that guy” it’s more of their mind being vigilant about dangerous opportunities, and not necessarily an endorsement of those possibilities. Kind of like how if you’ve ever picked up a really sharp kitchen knife you might think “it would be so easy to kill myself with this”, that’s not necessarily a “suicidal thought” but just the mind raising an alarm about a possibility + it’s actually out of concern for not dying that my brain raises the thought. So arguably this thought crossing people’s mind is actually out of an abundance of concern for safety. The morbid joking about it is probably after the fact, non-intuitive, and for almost all humans totally not thought in earnest.

I often have thoughts like this. It’s the worst kind of thoughts you can have. It s a kind of morbid curiosity, a call of the void. They usually only pop up for a fraction of a second and get immediately and automatically ignored. Any decent human being is supposed to repress those thoughts. It’s part of the human condition. Only politicians and psychopaths listen to those thoughts and act on them.
