I would categorize that with violent activities. You’re taking action that physically harms someone with an obvious causal chain.

Give me some leeway here, by the way—I am allowing myself to be “socratized”…

Indeed, I think you know exactly where I'm going with this question...

Poisoning someone is using physical force. Why would you think otherwise?

What if you are poisoning them through knowingly through by dumping toxic chemicals into the air or their water supply? That doesn’t require physical force.

That’s still wrong, whether or not it’s violent. What is your aim here?
