It's not "brilliant," it's an adult going after a not-fully-developed child.
I prefer just shooting the sickos and being done with them.
Devious would probably have been a better word than brilliant.
However, their capacity to think up endless ways to evade and perpetrate some would class as above 120 IQ.
But, yeah. Evil is terminally dumb in a list of ways.
And, terminating evil is a good thing.
The Blood of Jesus and becoming like Him is the only thing I know that does that well.
Hell just warehouses it.
