Honestly its sort of fair and just basic ass-covering. If some dummy out there gets the bright idea that they can kill someone because they’ll get a jury nullification anyway, and it turns out they discussed that here, it’s not great legally. No one wants to end up like 8chan.
No, they said jury nullification for future violent crimes, not violent crimes that have already happened.
i.e “Hey guys, do you think a jury would let me off for killing Scrooge McDuck?” or “I think juries should nullify if someone decides to drop a piano on Scrooge’s head” and such.
