This type of cockroach control is pretty par for the course in undergrad anatomy lab sections... I think the only part that seems weird is the gamification of making it a remote control app.
Do that in your kitchen and you get labelled a murderer.
Context is everything.
No, you don't. You get labeled a freak, and you may or may not be charged under health-related laws.
To be labelled a murderer, you have to kill someone.
(As an aside.. what purpose do you think your comment served? Do you really consider that I - the author - or anyone reading it didn't realize you have to kill someone to commit murder? It was an analogy, and I deliberately made it succinct. The point of the comment you replied to was "context is everything". To be fair, you have made that point rather well, although I suspect that wasn't deliberately.)
