Can’t wait to use phrases like “He was legally stealing a car” or “That guy was legally murdered”.
Depends on the way you define “have to”. If we take the loosest possible definition, as long as literally anything makes you do it, you have to do it. Could be another human, laws of physics or even your own brain doing stuff you don’t want it to do. In that case, I agree with you. However, people usually aren’t that loosey-goosey with their definitions.
Oh, just realized, this definition also encompasses the case where you want to do stuff. It’s all in the same category at this point. People do stuff because they have to.

You could get one of those fancy fake PhD papers printed out for you. It should say you got a degree in flatulometry from the university of Arse, Indonesia. Add more toilet puns just to make sure people stop by and actually read all of it when visiting your office where you have this paper on display.
That’s incredible. Do you have like a PhD in flatulometry?
Isn’t it evil enough that you don’t avoid evil actions? Is it necessary to take it a step further by intentionally favoring evil actions or even restricting yourself to exclusively evil behaviors.
Diagonal for the win!
So that’s a “yes“. Just as I thought! Although, with a sample size of just one, the result is hardly anecdotal, let alone statistically significant.
