Until quite recently, it was trivial to cheat on remotely proctored exams. All you had to do is spin up a VM, take the exam inside the VM, and use the host system to look up answers. I believe the main proctoring services now have crude VM checks. You can probably still use a KVM switch or a DP splitter and a buddy...
My point is that since it is so incredibly easy to cheat (despite countermeasures that are essentially theater), returning to in person exams is probably a good thing.
It's a dimension of neglect. If I run a service advertising itself as preventing people from harming themselves or each other (e.g. a mental health institution), then it would be criminally negligent of me to not limit people's access to sharp knives.
That is an excellent point. My recent coursework at Penn State, there were guardrails around cheating using Honor Lock, I am guessing a motivated student could find ways around it, but the system was better than trusting students to do the right thing.
The point you're making has nothing to do with anything the person you're responding to said, or with the OP. It's just a gratuitous description of sadism as a virtue-signalling imitation of seriousness.
You should find somebody who said cheating is fun and good to do, and explain your violent fantasies to them.
